I have no idea why this is happening and it literally just came out of the blue, and I seem to just do it. Lets see if I can explain it! Lately, if I'm listening to someone talk or whatever, If they say a world that has an L in it somewhere, or requires the use of their tongue, I will do it too. Its like I lip-read, but with my tongue. My mouth doesn't move, so I'm not mouthing anything, but its like my tongue will move as if I'm saying what they're saying, exactly when they say it. Does that make sense? Oh god, I hope it makes sense. I cant seem to stop, and it just happens! Is this a stim? If not, I have no idea what this is... :
