hypothetical black hole

Imagine if there was a girl you liked who was a bit down on her luck so you convinced her to come over to your nice house and have a meal. And she seems to be at least having a pleasant time but she keeps staring really hard at a blank spot on your wall and telling you what a beautiful window view you have. You definitely don't have a window there so you ask her to describe it and she just keeps saying it's so beautiful out there, and that she can see a person standing outside through it. Now, you're a little alarmed but also annoyed because this was supposed to be a nice date with just the two of you but she's definitely more interested in a person outside a window you can't even see, and it's becoming a bit of a problem because she keeps standing up and trying to walk through the wall. So you sit her back down on the couch and each time you do this she gets more and more upset because she really wants to climb through that window and she's mad that you won't open it for her, since it's your house and all. And you're definitely pissed off now because you don't understand why you and your very nice house aren't even enough to keep her attention for more than a few minutes at a time. And now she's just staring at the wall and saying the person is right there, and they're trying to tell her something important, but she doesn't know what it is. And in the end the most you can do is hold her on the couch next to you so that she doesn't try to walk through the wall again.
