Another source of 'presence'?

Sun behind treeMy acquaintance (MA) who has microsleep with REM (MWR) experiences, which resemble paranormal phenomena, was on a train recently, idly looking out of the window. Without looking round, MA was aware that someone sat down in the adjacent vacant seat. Then, suddenly, MA had the feeling characteristic of emerging from a MWR. Looking round, there was no one in the adjacent seat!

MWRs usually last for no more than a second or two and there was no one in the adjacent seat before or afterwards. It is therefore reasonable to conclude that the feeling of a 'presence' in the adjacent seat was entirely a product of the MWR. MA has not had this particular kind of MWR before. Previously ghostly figures have been plainly visible (see here for instance).

I have noted in the past that sound can induce a ghostly sense of presence, in me at least (see here and here for instance). Now it seems MWRs can also cause such feelings. Lab experiments have induced a sense of presence using the sense of touch. I suspect therefore that, like ghostly figure and UFO sightings, the sense of presence can have any one of a number of different causes.

MA also reports that MWRs appear to come of a particular type for several days running and then change to another type for the next few days. This pattern repeats endlessly. So, for instance, MA's recent MWRs have all consisted of bizarrely surreal scenes. Before that there were musical MWRs. Interestingly, the 'surreal' type MWRs corresponded to MA attending a concert. The MWRs appeared during certain songs, like a sort of pop video. Being surreal in content it was difficult to say if they were inspired by the music!

Without talking to other people who get MWRs, I can't know if having particular types of MWR for several days in a row is typical or unusual. Unfortunately, there is very little documentation on this sort of phenomena. It also explains why few anomaly researchers consider the idea that MWRs occurring to a witness unaware of their true cause might explain some strange phenomena reports.

From goose to ghost

Egyptian GooseWhen I saw this photo (right) I knew straight away something was wrong. What is strange is the object, resembling a pale leaf, in front of the goose. I have a bad memory but I know for sure that there was no object in front of the goose when I took the photo a couple of days previously. So what is going on?

I have reduced the photo to a small size here deliberately. It is similar to the size when I first noticed the 'leaf' object. As soon as I zoomed in on the photo the mystery was resolved. As can be seen in the cropped version of the photo (below right) the object is not in front of the goose at all. It is some kind of flat concrete object in the grass, possibly an inspection cover or something similar. I admit I did not notice it at the time but since it was behind the bird, rather than in front of it, I wouldn't have regarded it as important.

The concrete object appears to be in front of the goose, in the smaller version of the picture, because it more or less matches the colour of the bird's neck at that point. So, it is coincidence based on a number of factors coming together. There is the similarity of colouration between part of the bird's neck and concrete object. Then there is the relative position of the bird, concrete object and photographer which need to line up in very specific way for the 'leaf' to appear. Finally, there is the way the goose has two different colours in its neck! Even though I know what is causing the effect it still looks like a leaf in front of the goose in the smaller photo to me. That would make it that rarity, a photographic misperception (see here for more on this).

Egyptian Goose (detail)This is a good example of how a coincidence can make things appear quite different to reality. Such coincidences can certainly give rise to paranormal reports. While no one is likely to report a 'paranormal leaf', a different set of circumstances could give rise to an apparent human figure that would 'vanish' as soon as the witness changed position. This might easily be reported as a ghost. With a photo it is possible to examine the scene again and again and zoom in and enhance the image. But with a casual observation the first impression is the only one available, wrong or right.

Ghost investigation conference

Sun behind treeASSAP is running a conference concerned with ghost investigation on 1 April in Bristol (details here). Ghost investigation is, of course, a big thing these days. When I first started out in paranormal research it was all rather different. We would wait, sometimes months or even years, for someone to report a ghost sighting and then go and interview them. If the case seemed to merit it, we might hold a ghost vigil at the site of the sighting. However, such vigils seldom, if ever, produced any compelling evidence of paranormal activity.

In those days there were few instruments available. But there still and video cameras and audio recorders available, of course. Even with such basic equipment it was possible to find interesting evidence after the event. I never relished looking through hours of video of an empty room where nothing was happening but it had to be done. And, just occasionally, something was caught on camera. But there was a problem with this.

Suppose a witness on the vigil reported something unusual happening and the area was being monitored by a video camera. This was excellent because the video recording might give a good idea of what had really happened. This usually turned out to be either something mundane or nothing appeared on the recording for the relevant time at all.

Then there was the other type of event, more common, where something odd was noted on the recording but not by any witness at the time. Suppose, for instance, it was an unknown voice. Because no one present heard it at the time it would be labelled an EVP. However, it could be that it WAS heard at the time but not as a voice. It might have been recognised as an environmental sound, like shuffling paper, a creaking chair or someone knocking the microphone! It only sounded like a voice in the recording because it was formant noise (sounds with peaks in the frequency spectrum that happen, by chance, to form a harmonic ratio).

The same kind of thing could happen with vigil photographs. Anomalies might appear in photos that witnesses at the vigil didn't see at the time. Many of these were probably photographic artefacts caused by such things as overexposure, camera shake, objects out of focus, long exposures, etc. For an in-depth discussion of such photographic artefacts see here.

As this brief note shows, ghost investigation is a complex subject, fully justifying a conference.

A ghost returns!

ShadowI was startled recently by a dark figure lurking unexpectedly behind me. I shouldn't have been surprised really because it was the door ghost (background here) appearing in exactly the same place it always has. However, it has been a while since I've seen the ghost and I was not expecting it, or thinking about it, at all.


Last May I concluded that, after a long absence, the door ghost had gone forever (see here). But then it unexpectedly reappeared, just once, last September (see here). But that only seemed to be the exception that proved the rule. I decided the ghost had disappeared because I was approaching the door from a different direction from the way I used to. The solitary September reappearance was put down to the particular lighting on the day in question. So why has it reappeared this time?


The answer turned out to be simple. I was wearing a coat that I hardly ever wear. It has especially baggy sleeves, enlarging the apparent size of my arms. Since the ghostly figure is a misperception of my own hand and arm, this all makes sense. Indeed, it made me wonder. I used to wear that particular coat a lot more than I do nowadays. Could part of the reason why the ghost no longer appears much be related to that change in clothing?


Misperception is highly dependent on the exact circumstances of how an object is observed. There are a number of trigger factors (see here) involved that promote the misperception of an object as something else. But perhaps the most important factor in misperception is the apparent shape of the object being misperceived. I say 'apparent shape' because often it is not the true full shape of the object but a partially obscured view.


It will be interesting to see if the door ghost reappears again. If it does, I'm sure there will be some special factor, not always present, like the coat, that makes the difference.

Disappearing heron!

HeronAs a birder, I'm always on the look out for birds when travelling by public transport. It's amazing what you can spot in such circumstances when you try. I've even spotted rare birds in this way. So when I saw the crouching heron from a train recently I was delighted but hardly surprised. What happened next, though, was very surprising indeed.

The 'heron' suddenly disappeared to be replaced by what it truly was, a low white object resembling a (British) fire hydrant sign. I don't know if it really was a sign as the whole scene was soon out of sight. What astonished me was how absolutely perfect this particular misperception was. I was in absolutely no doubt, at the time, that I was looking at a heron and even tried to get a better view before it went out of sight. So when it suddenly changed into something else I was shocked. I've seen a lot of misperceptions in recent years but this was among the very best. I can't recall exactly how the misperception disappeared but it was rapid. The heron in the photo (right) doesn't look very rectangular, like the 'sign' (or whatever it was), but when crouching they have a quite different overall shape.

I saw another striking misperception from a different train just a couple of days later. This time it concerned the fence running alongside the railway. When I looked directly at it, the fence looked unremarkable. But if I looked up, so that the fence went into peripheral vision, the fence became a wall! If I looked back it was a fence once again. And if I looked up again, it became a wall again. As such, it was an unusually robust misperception.

Of course, misperceptions are quite common in peripheral vision but usually they disappear once you've seen them in central vision, even if you subsequently view them in peripheral vision again. I wonder if the motion of the train was adding to the robustness of the misperception. It makes me wonder if witness or object motion might be another misperception trigger? It would make sense as the other triggers limit how well an object is perceived.

Can you recount a strange experience too often?

Airbourne dustWhen I recount a strange experiences in this blog it is always a fresh memory so I'm pretty confident that it is about as accurate as my memory will allow. Indeed, the first thing I tend to do after having an anomalous experience is write it down. It turns out that this is probably the best way to get an accurate record of an experience. Sadly, many witnesses do not do this. Instead, they may tell many other people about their odd experience before contacting a paranormal investigator. And that is not good for accurate recall of an event.

Scientific research has shown that human memory works in an unexpected way. Every time you recall a memory it is stored all over again - a process called reconsolidation. The problem with this is that during reconsolidation a memory can be modified or even erased. So every time a witness recalls a strange experience they may reconsolidate it slightly differently. This means that if they recount their experience many times, it could be altered quite significantly from the original memory. However, the witness will not be aware of this. To them, their current memory is the same one they formed when they first experienced the strange event. It probably explains why, when you visit somewhere you haven't been for a while, it often looks different. It's not just because the place has actually changed, which might be true. The chances are, so has your memory of the location. I had this experience recently when I barely recognized a town I used to live in!

So, if paranormal researchers are interviewing witnesses they need to get some idea of how many times the account they are recording has been retold. A witness might, for instance, have seen a UFO a month ago but never mentioned it to anyone until talking to a ufologist. But they may have seen the UFO just a day ago but have talked about it with dozens of people. The former account might actually be more accurate than the latter one, despite the bigger lapse of time since the event.

The problem is that when people have strange experiences it is natural that they want to talk about them. The 'best' witness would record everything they could in writing and then contact a paranormal researcher straight away. Sadly that seldom, if ever, happens! And, with the advent of online social media, the problem of memories changing is probably getting worse! I wonder if the best advice for witnesses might be not to think about their experiences too much!

In other news, my acquaintance (MA) who gets microsleep with REM (MWR) has been hearing extracts from original musical compositions again. If only MA was a musician this could be a really useful ability (see here for an earlier account). And the photo (above right)? It is bits of airborne dust illuminated by a strong light. They are in focus and appear as light trails because they are moving - the exposure time was quite slow at 1/5s. So when I come across a similar odd photo in future, I'll know what to suspect!

Best ghost in months!

Shingle with turnstoneI looked up and straight away noticed something alarming. I was at a railway station and I could see someone standing just a couple of metres from the track some 20m up the line. The person was not wearing a high visibility vest so I guessed they should not have been there. The person looked small, probably not even an adult. At least the figure was clearly visible, I thought, so there was little chance a train driver would fail to see them. But then something else struck me. The figure was standing still - absolutely motionless - in an unnatural way. I suspected a ghost.

Apart from not moving, the ghost was impressively real-looking. I could see its clothing, face, hair and that it was facing towards the railway track. If I walked a couple of metres from my initial sighting spot, the figure vanished. So, a ghost then! But when I returned to my original position the ghost reappeared! It was, of course, a misperception but a strikingly persistent one. Indeed, I was able to study the figure for a while to see how it was made up.

The 'figure' consisted of a sign post, a tree stump and a patch of light vegetation immediately behind. Only when the three lined up correctly was there a human figure visible. At any other angle there was nothing remarkable to be seen at all. It was sheer coincidence that I happened to see these objects lined up 'correctly' when I first noticed them. Had I looked at the scene from any other position I would never have seen the ghost. Interestingly, the light patch of vegetation fitted precisely between the sign post and tree stump so that the figure stood out well against the darker surrounding background.

This was certainly an impressive ghost. Even after I KNEW it was a misperception I could still see it and it was very life-like. It was also an impressive coincidence. The figure was only visible from one precise position - the one where I first saw it. The tree slump, sign and light vegetation were all many metres distant from each other but happened to be in the same direction from the place where I was standing. Anyone investigating a sighting of this ghost would have been unlikely to come up with the correct explanation for the figure. They would have had to find the exact spot where the witness saw the ghost and hope that the lighting (overcast) was similar and that the vegetation hadn't changed much since the time of the original sighting.

The trouble with coincidence is that it can be difficult to unravel after the event. My experiences over the years have led me to conclude that coincidence is a much bigger factor in causing reports of anomalous phenomena than most people realize. The reason such coincidences are rarely discovered is because the factors that caused them rarely persist for long.

And the photo (above right)? It's meant to illustrate how we can miss things even when they are in plain sight.
