Nothing feels real?

i really want an explanation for this. ive looked up depersonalization and dissacociation and they both sound very extreme so i highly doubt i have either. days go by and i can't really recollect what happened during them or what i did. it's kind of like the opposite of an existential crisis. where i hear things that are important or life changing or that might make you think, it hits a wall and i never think about it. i don't really think about anything anymore? i never have an answer to "what's on your mind?" I pick a phrase or some words and think about them on repeat for some time, monotone droning in the background. then maybe i get distracted and pick a different phrase and do the same thing, whatever i was doing 15 seconds ago already forgotten. people seem weird and i don't quite think they're real either. i never come up with anything new, no original ideas, no creativity. like that few minutes after you wake up where everything's just like buzzing except for like 7 months straight.
