What is this purple circle on my arm?

Question

I woke up this morning and there was a small purple circle on the inside of my elbow (where it bends). There's also some smaller little specks, that resemble the rash you get when you over scratch something.

I haven't been scratching the area, it doesn't itch or hurt at all. What could this be?? It's kind of scary looking.

Answer 1

maybe ring worm

Answer 2

sometimes we do things while we sleep that we don't realize.  So you could have been scratching during your sleep.
