So I had this dream where I met the guy I had a crush on 2 years earlier. I hadn't seen him in the past 2 years. In that dream I saw him with a long hair, which I caressed. In real life, I know that he wouldn't keep a long hair. The person didn't look like him much but I just knew that was him. I might have forgotten how he looked like since he hardly have any social media presence. To be honest, we weren't even close back then our relationship had been mostly cordial. Nothing really happened in that dream except that it made me woke up feeling that I missed him so much. Much has happened since our last encounter and I hadn't really think about him in my waking moment for a long time. This stupid dream has thrown me into a depression now that I think I probably should have let my feelings for him be known. Maybe deep inside I have been agonizing over this regret and this dream was just an expression of it. This has been bothering me a lot. What should I do?
