I had a dream about the person I like?

I have had a few dreams with the person that I like in college, the girl that I like and see in my dreams, has a boyfriend. One time I dreamed about her like she was all upset, really down and it looked like she had been looking for me to tell me something and she told me that she likes me. In the dream I told her that she has a boyfriend but she said she didn’t want him but instead she said she likes me and she was crying and I catch her looking at me in college a lot of times? What can the dream possibly mean?

One other time again, I saw her in my dream, like I was back in my hometown where I finished secondary school and she was there as well and she was walking in the corridor she looked at me and she was upset again and then she put her head down and kept walking. After that a friend of mine that I used to have in my class, said you two definitely love each other? And to be honest I do like the girl a lot but I’ve never spoken to her.

What can these dreams about her possibly mean? Thanks :)
