there was this big red/black scratch
mark on my left foot.
it wasn't there last
night because when i went to the bathroom
before bed, nothing was on my foot.
and i sleep by myself. my bed doesnt have
anything sharp in it and im sure i didnt scratch myself.
but if had tripped on something, i would
have felt it. and its on the top front of my foot
NOT the soul. could there be a reasonable
explanation for this?

no, i dont have a cat or any other pets.
