Hi Misfit,
For me, I don't think that that is necessary. At least I'm hoping I guess. I had heard someone say once in here that the brain can process like memories so if that is true, then you would not have to.

When I am dissociating and T is talking to another part of my brain, I don't ever know what is said so I don't know what happens after that. I would think that I would need to have that memory while not dissociating in order to process it though.

I would definitely not try to uncover memories at this point in my life. I think if it's buried, there's a reason and when this part of my brain can handle it, then it will come forward. I went through some time where some things happened that majorly triggered some memories and I couldn't handle it at all. Those memories disappeared soon after and I am only left with the knowledge that I had some memories come and then disappear but even now, it terrifies me. I think for me pushing to find memories might get the same reaction.

Have you asked your T about it?
