Is floating of the ground real?

it has been said that if you can focus on a certain thing for a certain mount of time u can do anything but that is hard to do because u have to have total concentration and i do not know what percent of the brain u have to use to float of the ground but i wonder can it be done? i wonder this because when i was little i jumped of the bed and before i landed the ground i floated for like less then a second and i know this because right before my feet touched the floor i went up again before landing..criss angel has done it many times but i think when he does it is fake but i don't know...... so can it be done? oh and my friend well when she started to believe in god she was gonna do something stupid like jump off but before she jumped off she floating in the air and went back down but she said that was angels helping her (which i believe because if u believe in god miracles happen) so again can it be done?
