Continuing my trends of talking about weird things many of us have but didn't know was a condition, does anyone have a noticeable hypnic jerk? It's basically where right before you fall asleep, you have an involuntary jerk- larger than a traditional muscle twitch. It's an epileptic movement that occurs in many people, even those that don't have epilepsy. I probably have these at least a few times a month. I didn't know this was a condition until about six minutes ago.
