yes, when i was around 18-20 i had very strong deja vu all the time where i knew what would happen next, like I’ve lived it before. down to knowing the exact words/tone people were about to say, things they’d end up doing, etc.
now, I’ll get that same feeling but it doesn’t result in correct predictions anymore. no idea why it used to, but it was always weird.
when i was young, i was in a bad car accident where i had a head injury. someone stopped and held a shirt against my head and held my hand till the ambulance got there. I’ll never meet them, but I’ll never forget it.
