Last night when I was not quite asleep but dozing off, I started to hear a loud noise, like seagulls chattering, and it kept getting louder and louder. I started to feel really cold too and the quilt was down at my knees. Then I felt someone's hands grabbing my arm... :eek:
Naturally I was terrified out of my wits, then I suddenly found myself wrapped in my quilt, nobody there, no seagulls sound. I had woken up - it was a hypnagogic (the point between being awake and asleep) hallucination.
I used to get one about once a year - it was always in the morning on a day off when I dozed back to sleep after waking for a bit. It was never scary, well not really (daylight helped) and it would tend to involve me hearing someone calling me (usually someone I knew, not a strange voice) and coming into my room and nudging me awake, and I'd try to reply but couldn't (because of sleep paralysis).
But in recent times, it has happened to me twice very late at night when dozing off, and it's ****ing freaky!
It's mad how real it feels.
So I looked it up, and it's a thing all right - an unexplained neurological phenomenon, related to sleep paralysis. People hear, with bizarre vividness, doorbells, phones ringing, the sound of rustling bags (that's what I heard a few weeks ago), screaming, their names being called. The sensation of someone entering your room seems to happen in all instances, and sometimes there is the feeling of an entity pressing down on their chest (never had that one :eek:) which even has a term: "old hag phenomenon". A scary auld demonic bint going around visiting people.
I would imagine it's sometimes the basis of what are considered haunted houses. I remember reading a haunted house story about a girl who described the sound of paper crumpling while she was in bed at night, and getting louder and louder, which seems exactly like a sleep hallucination.

Anyone else got strange, spooky sleep experiences to share?
