This is a story that I heard from a senior soldier while I was in the military.
When that soldier was just a plain citizen, he used to know a really nice girl.
But suddenly one day, she started to have nightmares.
When she was sleeping, she could see a female that could only be considered a ghost who was crawling slowly down from the ceiling right down next to her.
It was too realistic to just be a dream.
As if she was stuck in sleep paralysis, the ghost would slowly come down until she could see every little detail of the ghost's skin.
Of course, she wasn't able to move or scream.
