Dreams are some mixup of things that happened during the day. No need to read too much into them. I've dreamt of work, people, hobbies including computer games and cherished activities not practised for years at the time of the dream. Dreaming of "stuff that happened", basically.

Dreaming of stuff that happened can be useful if you take it seriously. I often visit experiences in sleep which, when they happened, had led me to say to myself, "I should think about that, figure out what I could have done differently, what might have been going through their heads."

Evolution doesn't tend to waste things. As long as some processing is happening, it might as well be put to good use.
