Daydreaming and fantasy and imagination sometimes act as coping skills.At least for me they kept me sane and I survived horrific abuse.I Do not know which ones are useful and which ones are stupid.But it worked.I used to lay on the bed and imagine and daydream the opposite of what was happening in the reality. After sometime I felt ok and knew it was time to stop and come back to reality.I never consider it as a waste of time because it was much needed for me.
