While we sleep, our brains continue to work. That's just basic high school biology. They keep our heart and lungs working, and continue to interpret the information being relayed through our senses.
Often this information makes it into our dreams. So, those voices outside your window are assigned to people in your dream. That motorcycle backfiring outside your window becomes a gunshot. That gunshot outside your window also becomes a gunshot.
A few weeks ago, I awoke from a dream with a sore neck and shoulder. I had somehow ended up with my right arm trapped beneath me as I slept, causing mild trauma to my 42 year old muscles and ligaments. Then I began to recall the dream.
I was at Philadelphia's center city Turf Club. It's a combination restaurant & off track betting parlor. Although I haven't been there in years, I used to go there often when I was working near there 15-20 years ago. It's place that holds some indelible memories. So, it's a reasonable place for my dream to be set.
I was standing at the bar, staring up at a TV, watching a race I had bet on. As the horses came down the stretch, my horse surged to the front, only to be caught and passed right at the wire. A heartbreaking loss. In frustration, I furiously pounded my fist on the bar with such force that a shock wave travelled up my arm, and tore my shoulder from it's socket. First the joint cracked, then the muscle and skin tore. My severed arm dropped to the ground.
Panicked, I reached quickly down to retrieve it, catching my chin squarely on the bar. My neck tore open from front to back exposing my windpipe. My head remained attached to my body only by a few inches of skin and tendon around my spine. A Fishtown necktie.
Next I was in a hospital bed. Bandaged and braced from the chest up. Then, I woke up.
As this dream came rushing back to me, I realized that the dream was my brain was trying to interpret the shoulder and neck pain I was feeling. This was the story it came up with.
This is the brain I entrust my life to. This human mind. This miracle of evolution. This most sensitive and sophisticated biological instrument. It felt a bit of a twinge and said "Hmm. Neck and shoulder pain? I'll bet I know what happened there."
I imagined trying to explain to my brain, just how far off it was.
ME: Brain, you are not even close. Are you serious with that?
BRAIN: HA! Right. I know you too well. You and those horses. You
were at the Turf Club, weren't you?
ME: Are you my brain or my comic strip wife? Should I call you
"Pet?"
BRAIN: Touche'
ME: I wasn't at the Turf Club! I was just lying on my arm!
Come on. You're supposed to be all about logic, right?
BRAIN: (shrug) I think it's pretty plausible.
ME: Did you just shrug?
BRAIN: Yeppers.
ME: Look Brain, you must know I wasn't at the Turf Club,
because you are with me, literally, every single
moment of my life.
BRAIN: Hmm. I can't quite remember if we were there recently.
ME: I had a tiny pain, and this was the scenario you came
up with? A severed limb and and near decapitation? Really?
You don't think you're overreacting?
BRAIN: It's kind of my job to consider all the possibilities.
ME: Besides, Brain, look. My arm? Still attached. My neck? No
scars.
BRAIN: Okay, I guess maybe it didn't happen that way. Although,
they can do amazing things with cosmetics these days, so
I'm leaving the door open.
ME: WHY WOULD I LIE TO YOU ABOUT THIS?
I thought my brain had learned the lesson. But a few nights later my upstairs neighbor was having a small gathering. Through the evening occasionally their voices would rise with excitement and laughter. It continued off and on as I drifted off to sleep.
I dreamed I was standing with a crowd at a casino craps table. Cheering and shouting as the shooter cupped, shook, and threw the dice. "Come on seven! Come on eleven!"
I think my brain may have a gambling problem.
