A story I heard from a friend.

In the deep night, several friends split up into three cars, and headed for an abandoned hospital which is a famous spirit spot.
One person who didn't feel particularly frightened because of the number of people there said, "What the hell!! This isn't scary at all, nothing's even happening!!" and spewed some foul language on the way back to his car. Then, he got inside this car which was parked in the middle of the line, but however many times he turned the key, the engine wouldn't start...

He helplessly opened up the bonnet at once, and when he peered inside with a flashlight in his hand, there was something white constricting the wires of the engine.
"What... the hell is this...?"
Somehow, lily flowers were stuck in there. Five of them.
That friend immediately became frightened, and got into another of the two cars, driving away from that place in a hurry and leaving that car behind.

A day later, he went to retrieve his car with a repairman, but the lilies had vanished as if they were never there at all, and the engine started too...
