I get vivid nightmares. My most recent best was me flying. It was so real I woke up in a cold sweat. I even figured the area i flew over which is about 1 mile away on the top of a hill. My nightmares usually involve me being in extreme danger. I howl right before I kill some ridiculously dangerous person, before they get me. The fun part, my wife wakes me and usually my face is in front of her face. So she wakes up with me howelling in her face. And, this time the inducement is the cough medicine I am taking for my fading flu symptoms. I am certain it brings on the nightmares. You should hear me on Vicodin. I throw punches and wail & howel. I call it THurston howeling;get it?
