i don't know if you've read it but robert frost has a poem about picking apples so much that it messes with his head and he poetically hallucinates about apples. i guess my question is whether something like that has happened to you? i just binge watched firefly without thinking about it and now when i close my eyes it's like i'm still watching it sort of disorienting lol
yes, that's normal. if you do something all day, you will see visions of it, especially when you try to go to sleep. every thought you try to have will be shaped into the shape of that activity
