People with amputations often still feel pain in the amputated limbs. This is called phantom pain. A part of yourself that has always been there is missing. But it feels like it is still there.
I have phantom hair.
The other night I caught myself pulling the hair tie out of my hair. When I put on a T-shirt, my hands move automatically to the collar to pull my hair out. I put my glasses on so that no hair gets caught in the temples. When I take a shower, I try to be careful not to get water on my hair because I don't want to wash it. Jörg reports of similar events.
Speaking of showers - after my first shower after shaving, I was surprised to find something. I felt something like the shock of power. My sack hair is now longer than the one on my head
