I was in a toxic friendship that ended a few years ago. At the time, I didn't realize the friendship was toxic and so I was very upset and thought about them a lot for a long time. Now, for quite some time, I've been able to put them behind me and don't think of them much anymore. However, now they've started entering my dreams, but oddly, in a positive manner. They are always smiling, want to be near me and help me, and being nice to me. What does this mean, and is there any way I can stop it?
