In the dark of night, I would advise you to not look out your window. When you look out dark windows you see everything you have ever feared & everything you have ever dreaded. The impossible is possible and exists within the dark void. Nothing can be seen, but everything can be imagined. Ridiculous and surreal faces that look as if they know your deepest darkest secrets, decaying heads of the damned that moan and grunt and all your greatest fears do, in fact exist out there.
But don't worry. You are safe. It is merely a window, you can only see them, but they can't get you in your dimension.
But, there is one thing...
You are vulnerable, out in the open. What do I mean you may ask?
Your reflection; it allows you to co-exist with them.
Just don't blink.
