So do I, Duracell. I used to pretty regularly have dreams set in a Jurassic Park-type place. I remember one with talking velociraptors in cages, especially.
I used to never remember any dreams I had, but just recently they've started to become more vivid and realistic as well as memorable. I've been on the verge of lucid dreaming a couple of times, even (I get to the point where I realise that I am dreaming, but I've never done anything with that knowledge and the dream just continues).
It's really interesting, as I was always extremely skeptical about lucid dreaming and always figured people were just making it up, but it seems like it could be possible. The human mind is fantastic.
