I think I know what you mean, you are in a place you feel you know, and when you wake up you remember it like it's a totally alien place, yet in the dream you know this place.

I tell you, this woman was talking on the radio about past lives the other week, and she sounded pretty convincing. Things happening in people lives that trigger memories and stuff.

I have this reccuring dream, often its a different setting but occasionally they recur in the same place. It's like I am dreaming of a place I know, a city I have visited many times in my life, and I am walking around doing stuff in this city. Yet the strange thing is whilst I feel I recognise the place as a place I know, in the dream it looks completely different!

I've had this kind of dream where I am looking at myself in the mirror, and the reflection looking back at me is not my mine. One time it was a deceased relative, whose death I had a premonition about.
