Hamlet sees his father's ghost, but the ghost is invisible to Gertrude.
In Hamlet, when Gertrude mentions that Hamlet is bending his eye on vacancy, she means that he is staring at things that aren't there. The lines from the play are as follows: That you do bend your eye on vacancy And with th' incorporal air do hold discourse? So, he is seeing and talking to nothing (although we know he sees a ghost)... basically, she thinks he is hallucinating.
Hamlet is talking to the ghost of his father. Unfortunately for him, on this occasion, the ghost is visible and audible to Hamlet but not to anyone else, particularly Gertrude, who is sitting right beside him. She sees Hamlet talking to empty space, and asks him why he is looking at and talking to nothing. She is convinced that he's nuts: "This is the very coinage of your brain."
Hamlet is talking to the Ghost, which Gertrude can't see, which looks bizarre to her. For the first time, Gertrude sees Hamlet as seriously mentally ill, not just disturbed. Ironically, it's Gertrude whose perceptions are faulty in this scene.
I wanted to stay at a motel, but the one I went to didn't have a vacancy.
