For almost a year after a breakup from a LTR (he ghosted me after years together and I was in total shock), I couldn't even remember what the guy looked like. I doubt that I would have recognized him had I bumped into him in the street. 10 months after the breakup I had a dream about him, and I could see his face clearer than I had in real life. After that, I had two more dreams about him, but not as vivid as the first one. What could be the reason I'm getting these dreams after nearly a year?
