LMAO I do some shit similar to this. Sometimes when I'm riding on a bus I'll think really loudly in my head "I KNOW YOU'RE A TELEPATH I'M ON TO YOU!" with the hope that I scared the shit out of someone
I do that shit sometimes to. I think people can hear and see what im thinking so then i say in my head "whats up,i know you can har me." or "Look at me if you can hear me" and see if someone looks lol.
I also fight the air when nobodys around sometimes. Like i would picture someone i dont like and just swing off on the air pretending their there, ducking,bobbing and even acting like i got hit. Then i even have imaginary people break it up. Weird as shiy lol.
