Dream related

Okay, so im just going to put this out there, and would love opinions.
Around 5days or so ago, I had a dream of a guy I use to be somewhat friends with. I hadnt seen or even really thought of him in over two years.
The dream was really random, and was about him trying to get closer to me.
Ever since I woke up that day, I can't get him off my mind, and its actually really bugging me.
Any thoughts, or similar experiences on this? I am clueless.
Thank you for any thoughts :)
