yes i have just twice. the first one, i saw a street kid lying on the street after he fell on the underpass. i just saw his legs.
second, was when my friends and i visited a relative in the hospital. we parked our car at the back of the hospital and the only way up is to use the service elevator. and when we entered the elevator, a dead body came across us. we were all stunned and had goosebumps.....grrrrrrr
just hate it...
