Really strange dream about old crush?

[william]

ok so yesterday i had a strange dream. Inthe dream i was visiting a prison on what appeared to be a school field trip and while i was there i was that an old friend/almost girlfriend of mine was in there. and i remember that in the dream i was almost begging the warden or C.O i guess to let me speak to her, he decided to let me do it. when i got to what appeared to be her cell she was there. I tried talking to her but she wouldnt listen and wondered why i was even there. To answer her question and shut her up i kissed her, she didnt kiss me back but she didnt shove me off and she looked suprised. After that she was starting to talk to me but my time was up and when i refused to leave security cam and dragged me out. Ok whats weird about this is that i havent seen her in almost 3 years, she moved away, we never kept in touch, and we never got together. We never even kissed, so i want to know what does this dream mean? and also a girl i liked pretty much told me that she has no feelings for me whatsoever the day befor i had the dream so could dream have something to do with the girl i like rejecting me? I know this is long but could someone please try to help me, im really confused.
