I need help i don't know what's going on?

ok, i dk why im so hung up on this guy who isn't even real, i dream about him and think about him all the time, i know i said he isn't real but i didn't make him up, and i can hear his thoughts inside of mine. its crazy because he isn't evil and when im having troubled dreams he whispers in my ears "wake up" and i do. i feel like if though i love him and im almost sure i do love him actually i am sure not almost. and now i have a feeling he's real. Am I going insane or is this normal? Is it something else besides insanity? does anyone know why this is happening to me or just happening at all?
