i play out various scenes in my head, usually they have nothing to do with me. ever since i was 13 i also listen to a certain older song right before going to sleep, but that's because when i was younger i developed this weird and irrational fear that this one huge tree standing in front of the window in my bedroom can fall down and kill me so if that ever happened this song would be the last thing i ever watched/listened to. this habit has somehow stayed with me even if now i fully realise that being scared of something like that was dumb. these two things work no matter what even if it takes a long time
