interesting question, bitterdregs..

I actually have a voice in my head that chimes in whenever my mind starts spinning out of control and it calls me a liar and a faker and accuses me of inventing my problems and making them up. sometimes I believe it. but usually, I only believe it to make it shut up.

if I am DID (no Dx), then I am co-conscious. however, I did not consciously invent any alters. more like they appeared on their own and I met them. it took a few days before the one I have talked to would willingly talk to me and tell me her name though.

I have had moments where I start to 'wonder' things and as I wonder about them, related stuff will pop into my head - like I will wonder if 'x' happened and then I will have images pop into my head of it happening. however, with this other person/people (have noticed/sensed others) I did once wonder but it wasn't until much later (at a time I was not ruminating on it) that they appeared.

if anything, I find myself trying very hard to make them not exist. I try to make them go away, pretend they're not there, say they don't exist.. but they haven't left yet.

this is just my rather limited experience.
