I have had a dream the past three nights about the same person. Why?

There is a guy I like. I keep having dreams about him lately. The first night, I can’t really remember what it was i dreamed about, but he was in it. The second dream, HE TIED ME UP!? The third dream, I am in the back of a dollar store or something with him. What could these dreams mean? I am confused out of my mind.
