answer to your first paragraph question.....the only time this happened to me was when an alter integrated\became one \merged together with me. everything they were became me, so that opened the door to knowing more things, being able to understand more,

the rest or your post that you call "switching Conscious" my location calls being co conscious. (being aware that the others exist, being able to talk/converse with each other, participating with each each other, hearing the noises and chatter of the others....)

the feeling of switching from me to those I was aware off and then back to me like you describe my location calls the "revolving door" which also happened to me frequently as my alter prepared to integrate with me\become one whole person again...

but if I actually saw an alter like you would see a friend sitting across from you my treatment providers would call this a psychotic reaction, and usually an adjustment of my medications would solve the psychotic symptoms.

I cant diagnose but hazarding a ...guess....many of your more recent posts including this one seems to be pointing towards the possibility that you and your internal system are becoming one whole person again (integrating), only your treatment providers can tell you for sure if thats whats happening.

but regardless of why this is happening for you... may I say Im happy for being able to read about your journey and all the positive progress you are making.

I love reading posts on here where progress is being made. kind of lets readers know there is sunshine at the end of the hard work. Especially when i know someone who happens to be stuck in the moment and I feel bad for them then come on here and read the positive posts.

keep up the great work you are doing. happy for you.
