The most common theme I experience in my dreams are variations on the "exam nightmare". Unable to solve a problem, sleep in and miss the exam, unable to find the exam room on campus, forget my calculator etc.

Car accidents is another one.

The most freaky one was a variation on the "losing your teeth" dream. I had this dream during a stressful period when I was completing my undergraduate. My jaw closed shut and whenever I would try to resist the pressure would get greater and greater. It got to a point where my teeth shattered like pieces of ice in my mouth. The sound of the teeth grinding, rolling around inside your mouth and spitting them out felt so real.

I’m armed and I’m drinking. You don’t want to listen to advice from me, amigo.
