Dead to Me

I woke up in the middle of the night and couldn't feel my left arm. I mean nothing from my shoulder to my hand. When I used my right hand to touch it, it was freakish. Alarmed, I immediately got up, causing my left arm to swing around and hit my floor lamp and my left hand to then smack my face. Within a minute the tingles started, I could feel my arm again, and I fell back asleep.
