As far as I know, the only person here that has Sci-fi's is nesgirl119. Her experiences to me sound a lot like an OBE or maybe an LD in which you think you are having an OBE.

Anyway, lucid dreaming could explain either one. I suspect you will have a much easier time learning to lucid dream often than learning how to sci-fi. I believe her method involves inducing sleep paralysis and then fighting it.

Let me know if I can be of further assistance
