That's possible, I just decided for whatever reason that it wasn't likely to be an internal psycho-drama like that. I think because it was saying "we" and not "you," suggesting (but not denoting) that it is its own patient and not just some figment of the artist's mind or internal toybox, but you're right that it could be that they are both meant to be patients via both being the main character, meaning the "we" is more literally an "I" and I was indeed being too literal in my interpretation of the dialog, too.

Anyway, I am glad I gave you the opportunity to tell someone that ;)
