Both - I get stuck on the good and the bad. I have done a lot of work on letting myself free from the guilt and bad memories, but I still go there. I also real (sp?) into a fantasy world based on a past love I never got over, or happy times I felt very in touch spiritually. Hmm.. complicated I've never tried to articulate this. I'd just say i'm in my head a lot! Way more than I want to be! So this bella's lullaby song from twilight - it's awesome - only neutral memories - maybe that's why it works? And I love the pianist's talent.
