this is so interesting to me. apparently what many of us have always assumed to be movements seeping out from our dreams and into our bodies is actually our body automatically twitching to relearn the connection between body and brain.
rather than brain -> body, it's actually body -> brain! this is so cool to me. when our pets are twitching in their sleep it's their body sending signals to their brains like, "alright this is what we're working with. paws? check. ears? check."
