Is it normal to dream about the same person

I moved from the country I grew up in, and I had a 'friend' who I would hang out with at school. She was, tbh, kind of a (loser) and she didn't have any friends, so I hung out with her because I was lonely too. Of course, I did have other friends, and sometimes we'd joke about her, but she could take it, I guess. After I left, I don't remember if I told her where I was going. I have no contact to her, but I have dreamed about her 4 times already. The first two dreams, she was mad at me, the third dream, she wasn't really angry, the fourth dream, she was excited to see me. Maybe this is my subconscious making me feel guilty, but I don't know what I should do. (Also no one I know has contact to her)
