It just happened to me again but under way less paranormal conditions.
With thoughts of yesterdays events on my mind I went to bed partially intrigued by whether I could enter this state again, and partially frightened that I would. Each time I began to drift off I became scared that I'd wind up in this state, then realise I'm scared and no longer drifting off, and then be too worried to open my eyes in case I found I was already in this state.
Low and behold I started a dream. It's uncommon for me to remember dreams but I remember being sat on the floor as a kid, my parents and sister watching me as I removed some kind of bandage from my ankle. I'm no good with blood and I guess it looked pretty bad because I started shaking, an early sign of panic attack. At this point I for some reason decided to pretend I was in this paralysis state. I sort of hugged the floor, crawling along for a couple of seconds pretending I couldn't move much. At this point I remember them walking towards me, and that was it, I actually was in this state of paralysis. However in contradiction to my earlier event, this time I was fully aware of being asleep. I wasn't having this in the real world, I was having it in a dream. I was dreaming that I was in a state of paralysis.
At this point I realised the shaking and paralysis were real, even though I was in a dream and I couldn't open my eyes, the event itself was real. I had no experience of wind or any presence in the room this time, and I was in no way aware of conscousness.
Within a few more seconds i woke up to find once again my hair on end and a cold feeling.
This event was definately a dream. I link it in no way to paranormal activity, I simply conclude that my thoughts of the occurance the previous morning together with my lust for finding this state again, somehow allowed me to enter from a sleep. I dreamed my way in.
That said, if I can enter the state of mind and experience events with the firm understanding that this is a sleeping behaviour, then surely I must accept that the additional events and senses I had earlier were not of the state itself, but were of actual presence. I was in the same state of paralysis I've just experienced again, but instead of being asleep, where I should have been, I was wide awake and could use this state to sense something my normal conscious senses cannot detect. I must accept I sensed a real presence in the room, a real 'being'.
