What about harshly punitive father figure? And why age 5? Intriguing line of inquiry.
I arrived at age 5 based upon the location of the stored memories. It’s based upon observation of testing results, not just speculation.
My speculation or theory is that it is based upon the stage of psychological development child goes through at that age.
MS is an internalization of feminine consciousness. This is why more females get MS than males. I’ve noticed that the males that get MS tend to be softer or more feminine than most men. There is no judgement, just an observation.
I also noticed that the trauma for cutters or self mutilators was always around age 3.
