A childhood belief about physics

My sisters once told me that the Laws of Gravity are all relative, and that the only reason they work is because we are so convinced that they are true. So basically, if you forget about gravity, then you'll float/fly. They told me that to do this you have to trip and become so distracted that you forget all about the falling, the fact that the ground is coming up very quickly, and the fact that its going to hurt.

I decided to test this theory and went to the living room (which is a carpeted floor) and got my sister to throw pillows at me as I tripped. This was so I could become distracted and forget to fall. It didnt work and I became very distressed and finally gave up.

I still believed that I could fly if I was properly disctacted until my Dad, several months later, told me that they had made it up to make me do something stupid so that they could video tape it...
