If it counts, I occasionally have dreams about one of my ex-girlfriends, the one with whom I had my first serious relationship. A few of them involve me being isolated due to her presence, but the majority of them have us talking civilly with one another and resolving all of the tensions between us. In the latter, we become close friends once more, and frequently begin dating again, except that the relationship is far healthier and happier than it was the first time. Sometimes we're physically affectionate or even outright sexual with each other, but we're usually just happy together, sharing in the warm, fulfilling friendship that blossoms out of a good relationship.
I guess that, on some level, I still care about her and miss her; why would she keep showing up in my dreams otherwise, and why would the dreams have the aforementioned themes in common with each other?
I've never actually had a dream about someone that I've had a crush on but I did have a dream once about a girl that had a crush on me or so I was told by several people.
the funny thing was that I hadn't even seen her or thought about her in probably over year, but then she shows up all of a sudden out of the blue. It was kind of like when the ghost of Christmas past shows up to tell Scrooge "Hey Ebenezer, you fucked up!". Except she was here to tell me "Hey Distortion, you fucked up at your only opportunity to have a meaningful relationship with someone who actually cared about you and was genuinely interested in everything you had to say and didn't annoy the hell out of you."
the last time I ever saw her I was trying to avoid conversation with her so badly that I practically ran away from her. I only realized it afterwards it made me feel like a total dick. At the time I believe that emotions and friendships were waste of time, and therefore relationships were double waste of time.
I wish I could take back what I did, or at least apologize.
