Here, you stand with a door before you.

You know nothing of what is behind, but some odd, unwitting force is telling you to get the hell in there.

No light shines in its general direction, and there's no magic involved, but you get a feeling of unease knowing IT exists.

You are caught at a contrast, a dead end on the road of nothingness. Good, and evil.
The polarity gives you a headache,
and you aren't exactly sure which of these is behind that door.
You just know it to be something important.

Will you pass through it?
