I also had a dream, some woman was a policeman and she said we met before but I didn't remember, but I believed her. When I woke up I rememberd a dream, but could not tell if I ever dreamed this woman before.

In another, diferent dream I remember a dream before. It goes like this:
1. I dreamed i was in a car with my friends, it was night and we were driving close to sea. Somehow we crashed in sea and I begun to drawn. Water was green and dark. I was in panic and I woke up.
2. Few monts later I dreamed that I was in a bus with some people and bus was driving in some port, really too close to sea and somehow bus felt in sea. I begun to drown. Then I remembered first dream about this drawning, and woke up.
3. Again, few months later I dreamed similar thing. This time I was with my mum in a car, driving also near to sea, mum was driving too fast and we got of road, flying in air down to sea, and again i remembered having 1st and 2nd dream and woke up.
Scarry, isn't it ?
