I think it has a lot to do with dissociating when feeling unsafe, especially during non threatening moments. I remember when I would go in clinic for therapy and quiet rooms triggered me, seeing kids toys triggered me, except I didn’t know I was triggered and I would “come out of my body” and feel like I was in a dream. Also when my ptsd is triggered and I believe I am reliving the exact night that fucked me up, i regresa to acting like a 6 year old child, thumb sucking an all, having the vocabulary of a kid - but I don’t have revolution of this. Only my friends that saw me do this told me about it bc it concerned them. I only become this child like person when I am extremely drunk and heteronormative couples argue around me and that’s not frequent.
