What did realising you are not alone with yourself feel like for you? (Not asking for a diagnosis)

I dont even know if I'm using terms correctly, I barely know anything about DID, but this is the second time in my life I have felt like someone from inside of me talked to me and hugged me. I had a really bad anxious episode but I felt the warmth of a sun emerged from inside of me all of a sudden (so sorry for the vague expressions but this describes how I felt best). All I can say is that it felt like a mother figure and she said "i am so proud of you" very clearly and then hugged me. Before that could happen I completely zoomed out and just stared into nothing for a good 2 or 3 minutes. In between it also felt like I was zooming out and couldn't feel anything or focus or talk or think. Between derealising I felt like I was experiencing reality with different sets of eyes each. This was all so overwhelming. Sorry if this is extremely incoherent. But I have never felt safer and more filled with joy in my life.
What did the moment you realised you have DID feel like for you? I dont know what I did experience but I want to explore it more and also know how I can "reassure myself" like this again next time I feel so sad.
