Hole with light coming out of it

I got up in the middle of the night to get a drink of water. As I walked through the living room to get to the kitchen, I discovered a hole in the floor. There was light coming out of the hole.

I looked down in the hole and only saw light. I wanted to know more, so I said into the hole, “What’s this all about?”

The hole said, “What do you mean?”

I said, “Well, you weren’t here when I went to bed this evening.”

The hole said, “At that time I was elsewhere.”

I said, “Okay, but why have you come?”

The hole said, “No reason in particular.”

I said, “So, are you an omen, or something like that?”

The hole said, “Something is an omen only if you feel it’s an omen.”

I said, “To me you’re just a hole with light coming out of it.”
