Holes and worms under skin

An area 3 inches above my wrist suddenly had brown spots, I thought age spots. The area was sore when touched. Exiting a room I caught it on the door knob and looked down to see the skin had scraped off all layers of skin. I see holes and wierd live moving things in the tissue. Maybe I really am delusional, which scares me less than thoughts of being eaten up and full of holes like Swiss cheese. Tell me please, what do you see and is this normal? Feel free to say you see nothing and I am delusional.
