I have dreams which then at a later date are reenacted exactly as I remember them. Its never about anything terribly important, and its only about minutes at most, but is typically specific and long enough to convince me its not just a coincidence.
I don't believe its possible to have premonitions, logically it doesn't make sense for a person to see stuff before it happens. I figure its my mind fooling me, as the deja vu eureka moment only really comes at the end of specific parts of the dream.
I don't have many dreams (of which I rememebr), but they tend to be weird, and as I begin to realise this I wake up. I think its early stages of Lucid dreaming, but I've always been like this, and it doesn't seem to have progressed any.
Sometimes when I'm asleep, and not dreaming, I'm aware of whats happening around me. But it feels a bit like my consciousness has been supressed to a lower level, like background noise, but if realise this and can wake myself up if I so choose to. It feels weird and takes a few seconds, but its deffo not like being disturbed in a normal sleep.
