Well it's true that scientist's have been able to do it by manipulating what is called the Casimir force', kind of like reverse magnetism.

In the ancient world there were accounts of culture's being able to lift objects by banging large drums and chanting.

Scientists have also been able to replicate this 'acoustic' levitation although on a much smaller scale.

My own thoughts are that the ancient tales are massively exaggerated but that some people have been able to levitate either themselves or small objects by manipulating the forces mentioned above.

It's pure science not paranormal and it wouldn't suprise me if some ancient cultures and maybe even native cultures today are able to harness that power without realising the scientifics of it.

It's interesting stuff though I think.
