It's not 'insane and not grounded in reality' this is very possible, but as Fire Starter 666 said, you have to be advanced enough to do it. A very powerful mind and aura can make shit happen. I've seen much WEIRDER shit be done in real life, then just 'repel' bugs away. This is possible and can be done, and I'm pretty sure with an uplifted Kundalini and completing the Magnum Opus (Like a few of our High Priests and Priestesses did, if not all) you can do things like this with EASE, and much much more.
