Hm... after much thought (about five or so seconds after viewing this thread again...) I think that Telekenetics fall under the phrase "See what one wants to see". If I thought that there was a stranger following me, I'd begin to "notice" people around me acting shady and indeed following me. Another example is ghosts. People who believe in them claim to see them because they want to see them.
Dunno if this idea has been brought forth before or whatnot, but...meh.

Psi-balls may also be made due to lack of blood to the eyes or head, casuing one to see spots where they are focusing. And the part about being able to feel the energy on their fingers and though their body, I've practiced this and came up to one conclusion. If you think about/concentrate on a body part or section, you'll be able to "feel" more of what is going on with whatever body part you are thinking about. Kind of like thinking about breathing or walking... you start to notice things.

Again, I'm sorry if someone already posted this idea but... you know me, I can't help it.
