people seemingly make out dissociative amnesia out to be like what you'd experience passing out and staying asleep for 9 solid hours but in my experience it's far more like one of those nights where you're really struggling to sleep.
you wake up a few times halfway through the night you wander off to the bathroom before making it back and quickly falling back asleep. you hear some words and you think they're your partner but you might be imagining it. there's a loud banging noise but god knows where it's coming from. someone asks you about classes tomorrow but you don't remember if they really did or if you just imagined it. you go to the bathroom again only to realize once you're there that you never got up out of bed.
you wake up a few hours later and get on with your day. well aware of the time that passed but you're really not sure which bits were dreams or not, and if you don't think about it actively it'll probably fade from your memory before you realize. doesn't mean you don't remember some things or didn't notice the time pass, it's just really really messy
