The longest I've been awake for is probably about 4 days with maybe an hour or two sleep in the middle, at the end of it I collapsed onto my bed and slept for 12 hours which is probably the longest i've slept for ever.
I usually have between 3 - 7 hours of sleep a night, it depends. When I actually sleep it is usually a light sleep that I can be woken from if something like a piece of paper drops on the floor or something like that, I have sensitive hearing which makes it worse. When I actually have a deep sleep, i have horrible dreams where everything seems so real, I feel pain, taste, smell, everything I would do if I was awake and sometimes I wake up with unexplainable cuts on my body which i dreamed of getting whilst i was sleeping.
I used to have a reoccuring dream when I was 5 or 6 about being flying away to a crystal or ice palace in the clouds where I sat on a throne with my King who i'd never seen before whilst awake(The king is a man from a band in britain that wasn't around when I was 5, unexplainable to me) In my dream I was always older about 25 or thereabouts and I remember the dream used to reoccur each night and sometimes tart off from where I'd left off the night before, I remember where the dream ended because I was in an ice coffin but I wasn't dead and I could breathe fine, since then i've not had this dream.
I used to have bad dreams a lot too and I made this real weird sound when I woke up from these dreams, it was like a kind of strangled scream that I can't copy.
I remember one night terror i had when i was in the front of my house and I began to fly upwards towards the sky, there was a lightbulb in the sky and suddenly day became night, it was the scariest thing to me when I was sleeping but whilst awake I can never think why I was scared.
I fly a lot in my dreams and I seem to know what everything in my village looks like from birdseye view just from these dreams, i saw a copy of a photo of our village from a plane and it looks exactly like the dreams I had before i'd even seen the photo.
