It can be done, as a matter of fact, I did it so often when I was a kid that I got a school kid into psychiatry because I couldn't help myself... I always made his eraser fly up to his nose. But that wasn't enough, I levitated his pen and let it fly into his ear. Yeah, that was fun. Poor kid is being taken into the isolation chamber after numerous complaints. Ha ha ha, I guess that poor kid is still in some dark isolation room stuffed on tranquilizers and sedated. Oh well...
Didn't believe me? You better! Neither is the story of you being able to bend or lift objects with your mind.
To be honest, I learned a lot from Deepak Chopra, in a BAD way! He claimed the return of the Rishi's (Indian Wise Men) and how they possessed the power to levitate and fly around with super advanced meditation and willpower training. And guess what?
You can take a look at these stunts when you see a performance show nearby. Needless to say, you have to pay lots of money to see them AND I can guarantee you that on the show, something inexplicable will happen (some negative energy source, too much noise, "fill own reason in here", etc.) so that the levitation won't be possible.
I call that freak shows and rip off's. Nothing more, nothing less.
