"THE GHOST WHO SAW THE MAN ON THE BEACH" - 1986, Age 8 or 9

This is one of the more stranger stories I found. What on earth is it about?! I suspect I may have been recalling a vivid nightmare I'd had — I used to have a lot of bad dreams about ghosts, and camping in the dark. The ending is very abrupt too, so I may not have finished it.

The ghost who saw the man on the beach.

One night these people were in their tent and were hereing things.
One of the men went up on the hill and never came back. When April went by, the man came back as a ghost. The ghost told the men to go on the beach at full moon. The next night it was full moon. The man Peter went onto the beach and waited. After an hour a big face appeared in the sky. The face told Peter to tell John to go up on the hill.
