What you are experiencing is called co consciousness - being aware of the here and now at the same time as being aware of what is replaying in your mind. this happens envetually with all DID people that are in the healing and working on remembering waht happened to them regardless of what type of abuse it was that caused the person to dissociate.

Its definately a weird feeling. you will find lots of information in my blog about co consciousness and my experiences so far with being co conscious when remembering some of my forgotten pieces of memories.

hang in there. It is a weird feeling for sure but once you remember that forgotten memory the feeling soon passes. for now that memory is considered a normal stored in the conscious level of thinking just like a normal memory.
