Non period but personal problem

Ok I know this may weird but I have been having these really weird dreams almost as if they are real last night as I thought I was going to check on the puppy next to my bed I see a black man sitting there looking at me and I screamed and I was so scared and I look again and he was gone it's not the first dream either and I don't know if I am awake seeing this or if it's in a dream but it's one of the scariest feelings I have ever had has anyone else had this happen?
