@ Annie. There's a video here of a yogic flying competition. It looks more like a feat of strength rather than some sort of "static rise" since the competitors look jolly happy that they've made it rather than being oblivious, I.e. knee and arm strength to uplift the torso after many hours of training.
https://www.youtube.com/watch?v=jlw8CxTkyxA I asked some free runners on Silverdale how the heck they could do a jump (like a cat-like spring) to land themselves atop a 5ft pillar in one leap - answer being "many hours in the gym".
I don't know how your friend would counter that. A friend of mine, youngish and in no way dippy, believed her unseen friends were looking after her. Who am I to say they aren't? No point relating hearsay examples. Might also be in line with the view that we know things before our brain tells us we know them, i.e. agree the un-conscious mind knows more that it's cracking on.
@ Columbus - your post just in. I take supernatural to mean in your context something one can inexplicably do that I or most can't - not that it's heaven sent or in some way "out of this world" assistance. I wouldn't believe that card sharps can memorise two packs of cards and which have been laid down, but they can. Now (meaning modern enlightened times of figuring out
trickery instead of just standing back in awe) we know they can and many things can be explained or debunked. But can all of things?
