I once tried to summon a demon, using candles, a chant, and a seal copied from an old grimoire. Nothing very special happened, except I recalled someone from the dead. That sounds remarkable, but the miracle can be credited to the fact that this person never died in the first place: it just looked like they had. Still, one has to wonder if things would have turned out differently if I hadn't summoned that demon.
My second brush with the otherworldly involved telekinesis. Supposedly it did--more on that in a moment.
The first thing I did was put together a thing called a psiwheel. It sounds impressive, and it is: it's a piece of folded-up paper stuck on the end of a needle. Aided by this contraption, a psychic-in-training will gladly spend hours on end squinting, waving their hands, and muttering strange incantations, all in the dear hope of making a piece of paper move. Why anyone would go to all this trouble to do what a finger can do much better is of course a great mystery. In any case, I proved to be quite the prodigy. Within hours, I could make the psiwheel spin, reverse its motion, and cause it to twitch and jerk.
The next day I showed this trick to my family members, and rather than accuse me of witchcraft, their reactions varied from mild interest to indifference. A few hours later, I gave the whole thing up. I didn't see any point in teaching myself silly magic tricks, particularly when the whole endeavor had left me exhausted, as if I had run a marathon all day. And I stand by that decision--I have a million better things to do with my time than play with folded-up paper. Moreover (and here's where I bring in the "supposedly"), I'm not convinced I shouldn't credit my "powers" to psychology, static electricity, and air currents.
