I had a dream recently about someone I am no longer friends with. We had been good friends, but then we had had a very bad falling out.
In my dream, we were friends again, and everything was fine. I remember thinking in the dream how wonderful that felt, as though it was the way things were supposed to be.
Sometime the following day, I remembered the dream, and I also remembered that no, we are no longer friends. Interestingly, my waking self did not feel bad about this at all. I knew exactly why our friendship had fallen apart, and why I would no longer wish to be friends with this person.
And I realized that it was not the friend I missed, but the friendship.
