Last night, something happened in one of our dreams. It was a school dream, I was skipping in the halls, and one of the staff told me not to. I indicated I understood with an appropriate response, then a couple seconds later I went, "Wait, what did you say?" And the staff member (janitor, maybe?) was exasperated, asked me why I responded if I hadn't been listening. I immediately responded with something I knew on waking was honest and true: "Sometimes parts of my brain will get ahead of me, hearing, understanding, and responding to something without informing the rest of me." I didn't explain it in depth in the dream, but when I woke up, I knew it to be a Multiplicity issue. That in that particular part of the dream, Molly had processed what was said and responded, then forgot to tell the rest of us, so we were like "What's this now?" Now I'm awake, I realize this is something that happens sometimes in real life, and I think it came up in the dream because it happened several times the night before (along with several other, previously known brain glitches). Not with Molly per se, but it happened.
So yeah, if you know me in person and I ever respond to something you say and then say "Wait, what did you say?" (or something to that effect), sometimes it's because of an internal communication problem. (And other times, if the response was something as simple as "Uh huh," it's just the Autopilot responding, and we were too focused on something else to be listening.)
