I would say it's not true because you can't prove it, but it's not untrue because you can't disprove it, lol. But given how much time I think about hot celebrities I've never met, I seriously doubt it ;)
Do you not understand the concept of telepathy? Of course they are thinking about you. Did you just think that people can have their own thoughts when someone else is thinking about them? Well they can't.
I don't think so, like if I think about someone I don't know, I'm sure they won't be thinking about me. Even if the people I know, they may or may not be thinking about me when I'm thinking of them. Sounds like Telekinesis to me.
And people are saying that that kind of thing is telekinetic and FYI it's not. Telekinesis is moving physical objects with your mind, not putting your thoughts in another person's head. That's telepathic.
