These are so interesting. Sometimes they seem to walk a really fine line between 'dream' and 'reality'. I've had so many, that were so 'real' and memorable, that I don't know where to begin boring you with all of them. One is especially interesting though because it falls into a category I believe is called 'night paralysis'? Although it actually happened in daytime. It started as a a dream but continued into waking.
I was on the Greek island of Santorini - which is a pretty strange-feeling place because of its volcanic history - with a friend, who wasn't easy to travel with (nor was I, I'm sure!) so things between us were a little strained. We rented a little house in Oia for a few days, a one bedroom to save money. We lay down for a siesta nap, and I dreamt that something, a form of succubus, was stealing my life force. I recognised the feeling from another dream I'd had years earlier in which a witchy-looking woman with rune scars on her face put her hands on my face and started pulling the life force from me: I always felt I'd pulled away from her and woken up "just in time" from that one.
Anyway, in Greece, I awoke from this more vague but similar-feeling dream, to find myself terror-stricken and totally unable to move. There was a horrible weight to the paralysis. It was broad daylight still, I could see that through my eyelids, but couldn't open them. (I was DEFinitely awake at this point). My head was turned to my right; there was a malevolent presence next to my left ear, and a loud roaring sound in it, like the sound inside a seashell but with the volume at 11. The feeling that my life force was being stolen was still strong. It occurred to me, rather nonsensically, that if I could just connect with one other living being I would be saved. Through an immense effort of will I moved my foot a couple of inches and touched the leg of my sleeping friend with a toe. As soon as I did, everything - the sound, feeling, and general paralysis - vanished.
My friend slept on. I got up, shaking and in a cold sweat, and wandered the lanes of Oia trying to shake the fear and disturbance. A woman in a jewelry shop asked if I was okay, so I told her what had happened, thinking she'd find it strange. Instead she gave me a long look, told me that her island had "much mysteries and oddness", and insisted on giving me a 'blue eye' bead for my hoop earring at no charge, to keep the "curses and evils" away. I guess it worked because that never happened again.
