Whether any form of paranormal being is real or not is irrelevant to how the idea of them makes you feel.
The extent of how much one believes in that sort of stuff won't change how one would feel in the dark of the night,
alone and afraid.
But what exactly is it you are afraid of?
You don't know, and no one knows. It could be nothing. It could be your mind playing tricks. It could even be some
sort of demon or ghost.
You will never know though.
You can ponder it all night, or even for the rest of your life, but the fact of the matter is that you will never be certain.
And that's exactly what it wants.
So next time you feel afraid, just tell yourself its all in your head. It won't change a thing.
