Hello w.a.m....welcome to PC!
I would say that your description of your experiences sounds quite the same with me. Like having a comforter that calms you down saying soothing words...then she takes over and all the pain and bad memories disappear.
Trauma (not necessarily abuse) can happen as a baby such as a mother/child bond being broken or never made....no one could remember that.
This is something that should be checked out with a therapist...do you have a T?
Please stick around and ask questions if you like. You mention the word imagining...I guess we all go through that at first...the idea of not being alone in ones head is devastating with all the implications thereof and unbelievable at first. I too thought that at first...but we are a highly curious system...and got to know ourselves deeply.
I got to go to work now, so will check back in...hope to hear more.
