I'm sorry, I think that this would be something that you would have to talk to a therapist about. The only reference to regression that I can remember is "age regression" which is a process done through the use of hypnosis to take a subject back to a younger age.

There are plenty of multiples out there that don't realize that they are multiples. I was convinced that all the voices were just part of my systematic thinking process. We made a great thinker, but did a lousy job being a "normal" person.

But if I had to guess....couldn't dissociating from a trauma incident take one back to a time when one felt safe- like going back to baby times, secure in one's own crib under the protective watch of loving parents without a care in the world? Is this an alter?...I don't know. I'm thinking that normal people do this, but then again, like I know what a normal person feels like.

I do have littles, others that are babies up to tweens and teens that don't age that can present, but normally don't unless coaxed.

I wish I could help, but just can offer some possibilities or muddy things up even worse. Good luck!
