London, England, 1999:
Mr. Unknown was awakened sometime in the middle of the night by the louder than usual sounds of his neighbor's dog.
Being shaken from slumber, he had a very strange feeling, either from something odd going on outside, or the remnant of a bad dream. To rule out the former, he took a walk outside to see if he could pinpoint the cause of the dog's heightened state of alarm.
He was immediately drawn to a strange light in the sky. The light seemed to emanate from three spots, the brightest being in front of two others behind it, creating a triangular shape. He was staring at a triangle-shaped UFO.
