I remember being able to go back to sleep and resuming my dream. It usually happened if I reeeeeeeally wanted that to happen and kept thinking about the last part of the dream while going back to sleep.

I remember when I was like 13, I dreamt about a girl with white hair. Somehow I felt love with her in that dream, pretty wild. Anyways, we were just like hanging around and walking. When I woke up my "resuming" trick didn't work because I wasn't sleepy. I still remember her and it was a dream I had more than 15 years ago.

I had recurrent dreams, like dreams that I knew I had already dreamt, but the white haired girl never repeated.
