When I'm deep in thought, I will sometimes have a short, convulsive shiver for no particular reason. It's strong enough to be visible to people nearby, and unnerving to some of them. I don't know if that counts as my mind, but it is weird.

I am very interested in my dreams, and make a point of remembering interesting facts about them whenever possible. I have vivid dreams with a wider range of sensations than anyone else I know, including: color, sound, texture, proprioception, sense of falling, the sensation of having something disgusting touching me (does anyone else get that as a distinct sensation?), realistic vomiting, occasional lucid dreams, and occasional metacognition during non-lucid dreaming. I don't have all of those in any given dream, but I have experienced most of them in the past year and all at least once.

When I have falling dreams, I (sometimes?) jackknife my actual body into the air such that it hits the mattress when my dream body lands and I wake up. I know this because I once woke up on purpose in the middle of falling and caught myself doing it.
