Nope, I don’t feel anything different with my tongue, either. Just feels I’m touching it where I’m touching it.
I’ve noticed some kind of odd tricks over the years, though, that I think have to do with momentary proprioception confusions.
Here’s an example that’s easy enough to replicate. Sit criss-cross (doesn’t matter which leg over which). Reach your hands under your thighs to grab the toes of each foot. Pay attention to your right hand. Without thinking too hard, move the foot in your right hand.
Which one did you move?
…
I know another trick, too, that was a game I learned from kids growing up. Find a door frame, and stand in the middle of it, with your palms against your legs. Keep your palms facing your legs, and slowly lift your arms until the backs of your hands press against the door frame. Now, for a count of 30–60 (just depends) press as hard as you can into the door frame, like you’re trying to lift your arms all the way up to above your head. After the time, step out from the door frame, and notice what happens to your arms.
(If you don’t have a door frame, you can do a “mini” version. Keeping your fingers straight, pinch them all together on one hand (making the shape you would with a sock puppet, or that you’d bring to your lips to indicate “food” in sign language). Wrap your other hand around the fingers and squeeze. For a count of 30, press outward as hard as you can with your “sock puppet” hand, against the squeezing hand. Let go, and notice what happens to your fingers.)
