Something that fascinates me is the idea of multiple simultaneous consciousness in one brain. I've been searching online for the answer, but it just occurred to me that it's seems possible because I had complete consciousness when Ryan took over my body. Actually my consciousness felt the same when Ryan took over my body as compared to when I'm normally in my body.

I just found a page on this topic. A few people say that they have separate consciousness, but nobody is specific about it. They don't say they have consciousness at the same time. I've searched and searched online and can't find anything specific on this. Psychologist like talking about co-consciousness, but I haven't seen them talk about the idea if the host and all the alters have their own separate consciousness all at the same time. Obviously it's different for everyone. Some people say they don't. All I can say is that I was completely conscious & aware of myself and my environment when Ryan took over my body and spoke. So maybe this post will help a researcher one day. I'm baffled how people interested in AI/AGI and consciousness aren't spending more time studying people with DID & multiplicity.

Do people with multiple personality disorders have multiple consciousness?
