I’m not sure, but I think a caffeine deficiency can keep my unconscious mind awake. It’s a little bit like having a college roommate who has a schedule opposite to your own. You know about each other’s existence and you may occasionally leave notes for one another, but you never actually sit in the same room. You walk in, see the state of the apartment and wonder, “What happened here?” or “What was he thinking?” or “How did melted cheese end up there?”
I don’t know about yours, but my unconscious self usually keeps to himself. Most of the time, he’ll stay in his part of my brain with the lights off. However, on those occasions where I’ve been too busy to down the minimum amount of coffee for the day, my conscious mind will get drowsy and my unconscious self will emerge from his crawlspace. We’ll exchange uncomfortable pleasantries and he’ll complain about the excessive quietness. We’ll both eye the dishes in the sink and then one of us will change the subject.
He’ll close the window blinds, turn off as many lights as possible, and slink into the shadows. His eyes glow just a bit, so the net effect is a tad unnerving. “Are you awake?” he’ll whisper. I’m not always sure what he hopes the answer will be. I’ll usually pull myself up and pretend that I’m fully alert. While not convinced, he will usually make some excuse and then slip back into his crawlspace. Just before closing the trapdoor, he’ll say, “Stay out of my room. You wouldn’t like what you’d see.” The door will creak closed and metal will scrape as heavy locks grind closed.
“Right,” I’ll declare. “…As if I’d want to see your lair.” He knows I do. However, I know that he knows that I do and that he still got away without doing his own dishes or explaining what happened to the couch. I’ll pour some more coffee and rub the sleep from my eyes. “That should knock him out for a few hours,” I’ll crow. Deep down, I know that it’s only a temporary fix and that as soon as I fall asleep, he’ll sneak out and lurk, unrestrained, throughout my brain.
That reminds me, I’m going to leave him a note telling him to stop using all of my cheese.
