I was wondering if this happens to anyone?

Hi i’m diagnosed with schizophrenia and partial D.I.D and i was wondering when you’re co conscious with an alter if images change? i’m co conscious with my alter sometimes and images change and i’m wondering if it has something to do with my brain not seeing a full image properly? If that makes any sense? Like my alter sees the image properly and I don’t? I’ve told my doctor a little bit about it but she doesn’t understand.
