I've done the cloud thing too...but I didn't punch holes in them, I made them gradually vanish (over a period of say, a minute or two). I did it with smaller clouds, because I didn't have enough confidence to take on the big ones, so I just made little clouds vanish. This was way back in the late 70's. It takes focus and concentration. Anyone who's got those, plus a little confidence, can do it. Most people don't imagine they can do it, so they don't try it...or if they do (at someone's suggestion) they don't try it with any confidence whatsoever...and accordingly the results match their expectations...perfectly. Nothing happens. :-) It kind of works that way with most things in life.
