Weird dream event thing

Hey guys, I’m trying to understand something that happens when I sleep sometimes.

I’ve noticed that after parties or very social and stimulating events I’ll wake up but still be dreaming. My dream will usually be along the lines of being in a social context (like the parties still happening) but I’m asleep in my bed. At the same time I can see my surroundings (in my bed) but my minds all messed up. It happened last night after a green day concert an I woke up and felt awake for half an hour but I was mentally at an after party.

Does anyone know what this is. Hope everyone has a good day!

TLDR: weird dream phenomena where I’m awake but mentally somewhere else and I can’t fall asleep for a while
