Is dreamless sleep a rehearsal for death, or a reminder of what came before life?

Anyway, I’m awake again. I dreamt I was at a kindergarten and two different women* were hitting on me (it was awkward), then they had to leave.

* I remember one of them being French. She was thin and wanted to play tennis. I was about to play myself, wearing a bandana, with my father standing next to me (he was sort of impressed by the situation, I think she was his type). She said she wanted to talk to me because we were of the same kind, which she claimed she could see from a long distance.

Later, at the kindergarten party, she explained that she drove trains and lived in Örebro. She had experienced a newly built tunnel that was exceptionally good. Apparently, it had been a total thrill for a train driver.
