Many children dissociate when something is going on around them that seems scary, or not right. It is a coping mechanism. So, sure it is possible that, it did happen. When, I talked to my T about my lack of emotions towards the rape that happened to me, and lack of emotional response from myself when it happened to me at 10 years old, it said it was b/c I dissociated and was not in touch with my body during the trauma as a way to keep me safe.
