Back when I lived in the PI I was a boy scout.

Our troop decides to camp in the playground of our school, which I was told used to be a cemetery back in the early 1900s. So we were woken up at 3AM. My buddy and I head inside the school to wash our faces in the bathroom. When we got out, I looked all the way down the hall to another row of classrooms and I saw this white figure walk out of the stairwell and across the hall. It looked like a plain white cloak but the face area was all black.

Both of us saw it and we ran screaming back to the tents...haha.
