The kinesthetic sense is one of your internal senses. It tells you the position of your body. https://en.wikipedia.org/wiki/Proprioception

With intense focus you can trick it so it feels like your body is in a different position than it is. But you usually still know your body's true position from other senses so it ends up feeling like you're in two positions at the same time.

It's quite trippy.

Never heard of that. Trippy. I always wanted to try the Crane and Piantanida experiment to see what those colors looked like. Was afraid it would screw up my brain haha.
