Don't open the door

> Is there anything else in the room aside from yourself and the light? Is there any other door besides the one with the sign on it?

Once again you look around the room, but can't find anything else. There is only the remaining light on the ceiling and the door here. You look at the door again.

It's just a normal regular wooden door.

There was indeed a sign that said not to open it, but that doesn't mean something bad will happen if you do.
For all you know, this could just be a closet or something...

You're getting more and more curious about what's behind this door.
