no I never saw any of my alters in my mind nor outside my mind. I did have some situations where I thought I did and it turned out to be psychosis and hallucinations, where based on what I knew about my alters my mind would hallucinate, or have delusional thoughts that I was seeing them.

I found out that for me it was hallucinations / delusions /psychosis by talking with my treatment providers. they told me that any time something new or sudden happens, that hasnt been happening for years is not usually part of my DID and dissociative disorders. they made some changes to my medications and I was back on track again.

the brain is an amazing thing and it can create images in the mind of all kinds, whether by daydreaming, hallucinations and what ever else that can cause this kind of things.

my suggestion contact your treatment providers, they can help you with this.
