I can't think of any similar occurrence from my childhood. I grew up with a "functioning alcoholic" mother and 2 younger siblings. Nothing too traumatic happened that I can remember. Things were always financially unstable and my mother was mentally and emotionally abusive (which escalated horrifically after I turned 18) and while I would now classify her treatment of us as abusive, at the time it never occured to me that anythibg was wrong.
So perhaps what I experienced was not DID. Thank you for the insight!
