Are dreams trying to tell you something?

So I woke up from a dream about a former friend and former crush from forever ago tonight. The dream was that he proposed to me and we were engaged to be married. I even remembered the kiss we shared and the ring was heart shaped opal gem with 2 heart shaped diamond hearts. In the dream he said he wanted to do it publicly so that people knew that he was serious about marrying me. I also have not seen this guy in years so why dream of him now.
