had the weirdest dream last night

basically the dream starts with me in a cemetery preparing to die. but first i run a test to make sure that the funeral process goes well, so i lay in a coffin as if i were dead then i get burried (still alive). after a while of just laying there i get dug back up and get out of the coffin. then i just wait for my death. i spend time with loved ones and saying my final goodbyes, but as time goes on nothing happens. i know my death is coming, so why am i not dead yet? i obviously feel nervous but sure that im supposed to die. then i wake up. the dream felt so realistic that for a second i still thought that i was supposed to die, but i quickly came to my senses, then became confused cause wtf just happened lmao??? it was still pretty early in the morning so i went back to sleep and had another dream i cant rly remember, but thats not relevant. i also left out some other details i cant rly remember, the dream was more complex and lengthy than this but i sorta forgot most of it. im pretty sure there was another person before me who went through the same process but they actually died. i think it was my mom? honestly its all a big blur but it was something along these lines o_o but anyways this dream kinda creeped me out because i havent been thinking about death or anything, nor do i often have dreams like this so what could the reason behind this weird dream be??
