Why is there 3 random scratches on my neck?

It wasn't there when i woke up, but about 5 minutes after I got out of my bed I felt something sting my neck and I noticed them. They look like cat scratches. I looked online to see if i could find anything, and people keep mentioning demons and that shit is not funny, because i'm fr scared to go to sleep, now.
