Thank you for your replies. I haven't really spoken to anyone about my dreams as I really wouldnt know where to start. I did mention them to my psychiatrist about 6 months ago and I was told it was normal! The dreams are regular as clockwork, every night without fail. Often I only remember little bits but sometimes I remember it so vividly that for a good part of the day once ive woken up, I find it hard to distinguish between what is real and what was the dream. Bizarre! I was always told as a child that I had an overactive imagination, which showed through my childhood "invisible friends". I guess its just a continuation of that.
If only one night, just once.. I could dream about the lottery numbers...
