Yellowstone Caldera

[Dreamcat]

Dream I had last night: I was viewing a scientific presentation of a picture on a screen that was a scientist using his left hand to do something to the caldera of Yellowstone where some smoke was coming out. It seemed like a simple scientific talk, with a scientist in a white lab coat who was explaining the photograph. I interupted him saying, aren't you right handed? (He was pointing to the photo with his right hand, and in the photo he was doing something to the top of the caldera with his left). He looked at me and then photo and his face blanched. He said something to the effect that if the photo is showing him as left handed then the photo is reversed, and that means that this isn't just smoke coming out of the caldera, this is an emergency, it looks like it's going to blow.

I woke up shortly after that.
