I had a stroke roughly eleven years ago. When the stroke started, I got really creeped out. I was in an elevator and I thought a stranger was reaching around me from behind to grab me. It was my right arm. I cracked a joke about it, I didn't know it, but I wasn't soeaking. Just mumbling and making creepy gutteral noises when I thought I was laughing. Then the face droop. Followed by my right hand becoming locked in a fist. It took months on rehab to get it open. And it lost a lot of function.
