One of the few dreams I remember in vivid detail is related to this: I make a joke to a little alien like the one in the crop circle. To correct my lack of focus he projects a sound at me that increases in amplitude, incapacitates me and causes my brain and sinuses to vibrate.

When I woke up, my sinuses tingled for an hour. And I have vowed not to try to joke with aliens if I ever meet one.
