I have avoidant personality disorder, and this is a repercussion. Both rumination and daydreaming. The daydreaming isn't immediately harmful in itself, except that I should be doing things and living life instead of being lost in my head. It's gotten better as I've tried to limit it and engaged in more activities.

Sorry, that's all I've got at the right now -- I'm sick at the moment and so awfully tired and fuzzy-brained.
