re: Are dreams the most unexplained human activity?

Last night I dreamed me and a girl I went on two dates with probably 20 years ago were on a ski trip and having a good time. The dream went on for prob a week and before I woke up at some point I started wondering about my real life wife and if she would find out.

Note, I don’t even remember this girls name, just face. Nothing memorable and haven’t thought about that person since our last random date decades ago. I’ve also never cheated or thought about realistically cheating on my wife.
