As I was doing the blending work between alters, I was actually feeling my brain doing things - It felt like jolts of electricity in there between different parts. I didn't think the brain could feel things but T said that what I told him matched the areas of the brain that would be active for those alters we were blending. He thought the hypersensitivity I have as a result of the PTSD allowed me to feel what was really going on in my brain :-)
