Lockjaw
Last night I dreamed that I was running around a place where I lived, not my current apartment, but a place with blue overtones and lots of shadows. I couldn't open my mouth, and I was having trouble breathing. My teeth were stuck together, and I was panicked. Every time I tried to open my mouth, the connecting joint of my left jawbone clicked and I gave up. Trying any harder might have popped it out of socket. I drew full breaths, but it was with definite effort.
Then I woke up. It was 2:20am. I was lying on my right side, and my left arm was wound around my right shoulder as if attempting to grab my right shoulder blade while I slept. My left bicep pushed hard enough against my neck to cause trouble breathing and hard enough against the underside of my chin to hold my mouth closed.
I wonder what my left hand was reaching for.
