Dream of

Whenever I have a bad day, I always dream of my childhood friend Joe F. It's not like I hated him, or the thought of him brings up any negative thoughts, we were very close, like siblings. But no matter what, if I go to bed angry or sore or especially exhuasted, Joe F. will show up in my dream. In the dream, he'll act towards me in a romantic matter. It's really weird; what does that mean?
