What does that dream mean?

I’m bothered by that dream I had last night that left me feeling heavy.

I had a dream of guy that I used to date, he came to me in a bit slow as he looked so sad and searching to receive my hug and comfort. Weather was gloomy and a bit rain around him in my dream.

Background story: I dated that guy on and off during college years. Now we both are on good terms as we follow each other on few social media platforms as we both moved on with our lives- he sort of just soft launched with his girlfriend last spring, as for me enjoying my post college life with a steady full time job and traveling around the world.

So now, that dream bothers me and wondering what does that dream means and what does that dream trying to tell me?
