Here's something which has both intrigued and bothered me for a while and I'm looking for people's ideas on it; I have some thoughts of my own on the subject but wonder what people might think...
Ever since I can remember I had encounters with a spirit which only I ever saw or detected; later on that changed but I'll break it down into periods of time so as to help it make sense.
From age 6-9; I used to, once a week on a Friday night encounter the image of a little boy, my age and roughly my size at the time, who would sit on my bed and try to tell me something. Only I could never be sure of what he was saying as it was fragmented as if he were a badly tuned TV or radio station; thus I could catch only snatched or mangled words. Also, he was made of static, or interference; I could see his basic shape but no details or facial features. But he moved and gestured and was fully three dimensional. I once or twice saw the actual ghost (I think) of the same boy run past the foot of the stairs at night but again, I never saw his face.
From age 10-12; I would encounter other examples of the same spirit on the street during daylight, just a flicker out of the corner of my eye; dressed like me and almost resembling me.
From age 15 onward; people in a number of locations swore that they saw me or spoke to me in a place where I either had never been or when I was somewhere else, miles away at the time. In Barcelona, Spain in 1997 (aged 21) I was with my then girlfriend on the Metro and she suddenly grabbed my arm and, unable to speak, directed me to look at a guy at the end of the carriage in front of us (we were at the window at the far end of our carriage, he at the same at the back end of his)...I looked and, for some reason could not see his face but she swore he was my twin; I could see he was dressed like me and had the same build as I did but not his face.
In Coventry, England, on three separate occasions, by three separate people over 5 years, the same guy (or spirit) was seen by different people who knew me very well. He even reacted to my name being called once; called out to and waved to an ex's mother by name and to the ex herself then later disappeared on one occasion. He got me into trouble once or twice as he turned up in locations I was not and got me accused of either lying or ignoring people. Each time I was somewhere fairly far away, nowhere near the location he was seen.
I have never seen him myself but starting this period, off and on to the present, I had a series of dreams where I would meet with and converse with someone, within a group of characters but, upon waking I would remember the entire dream EXCEPT the name, face and whole conversation I had with that one person; every other detail and conversation I had with anyone else in the dream I could remember with crystal clarity.
The whole thing is that my double has been seen by a lot of people who knew me both extremely well and intimately who resembled me exactly in hairstyle, dress, facial hair, (sometimes) speech and mannerisms AND on at least one occasion seemed to know people I knew but I have never seen him myself. Any occasion I may have encountered him I have either completely forgotten it (with obvious memory holes and gaps) or been unable to see his face... Almost as if I am not supposed to recognise or see him... Bugs the hell out of me!
I have been told a number of feasible ideas; he's my doppelganger, my lost twin or; and this is the interesting one; something which happened at my birth (I almost died at birth); that a part of my soul was broken off and has now somehow developed an independent existence of it's own; hence I cannot see this "him" because he is, in fact, me... A copy of my own soul. So just as science fiction would have us believe that you cannot see your past self, maybe you cannot see your own soul shard (if we believe that a soul is like an earthworm, if you chop it in half you got too halves which grow into two independent individuals). Am I seeing (or not seeing really) my doppelganger or a part of my very own self?
