im not sure if this is the right place to ask so remove it if not (i had a look for a body unexplained/weird body stuff subreddit but couldnt find one)

does anyone else sometimes feel like they almost disappear for hours at a time even though they havent actually gone anywhere ? so for example i can be laying in my bed at 12am watching tv or drawing or on my phone then its almost like within a second its 3:30am and i literally cant recount what ive been doing in the past few hours. again i dont know if this is the right place to speak about it and ive asked people if theyve been through it but no one seems to know what i mean. its like ive disappeared for a while and it can happen for up for 4/5 hours and its like i blink and suddenly its getting light outside but i dont know where the times gone or what ive been doing. anyone else ?
