Something really weird just happened to me. I was sitting down working on my computer, focused on work, and my body did sort of like an odd hiccup type thing, but not quite a hiccup but more like a rapid deep breath and exhale, and then SMOKE came out of my mouth! A good amount of smoke. Very distinct from the air.
It's 75 degrees right now - it's not cold. I don't know that my body has ever done something that weird before. Certainly not that I remember.
