I don't know what to make of this. A driver in Surrey (England) emerged to deal with a fault in his car. Then he experienced a horrible smell, like that of the stink-bomb favored by prankish schoolchildren. Getting back into the car, he saw a face staring through the window.It was white and he could not see eyes, nose or mouth. The head was white, but the body, which was shaped like a bell, was dark. The estimated height of the creature was4'6".
This episode occurred in 1967.
