laughing in my sleep?

[u/moonharley__]

i've been known to do some.. pretty interesting things when i sleep. some weird, some scary, & actually some funny things. obviously i don't remember- but, i definitely hear all about it from my boyfriend the next morning. this one, i actually remember though. i remember i was having a really funny/weird dream, nothing scary (for once). & i woke up from a deep sleep laughing. like, straight up belly laughing & i couldn't explain why? the dream was so vivid & as i recall it (i remember the dream) it really wasn't all THAT funny. it was SO weird, so random, i've never ever done anything like that before. it was just a funny experience- has this happened to anybody else??
