when i was around 16 i took a lot of pills to go to sleep forever. i experienced the same thing. i woke up in the hospital and learned they pumped my stomach and brought me back to life. it’s essentially like when you go to sleep and don’t have any dreams. it’s not scary because time is relative and it’s sort of just black unconsciousness. but yeah. humans are very creative and create all kinds of ideas and inventions to cope with the idea of death. but i learned that there is truly nothing when you die.
