Actually the 10% usage of the brain is a fact of biology, I believe, rather than a myth of psychology. I can clearly my AP biology teacher talking about it... and my psychology teacher too, I think.
I'm not really all that familiar with this subject. I've seen a few shows featuring twins who were raised apart, but had incredibly similar likes, dislikes, hobbies, etc. though. That was pretty interesting.
Anyway, I don't exactly know if I'd call these feelings/bonds/whatever telepathy, as I think we're all connected in some way, but I don't believe it's possible for someone to literally know what someone is thinking/feeling--reading someone's mind. But I do believe it's possible to sense it/get vibes from seemingly no where. Or something. Not sure how to explain what that means. You know, that "Something tells me there's something bad going to happen to so and so" feeling.
