is Macbeth mad in 2.1

 

Macbeth is mad this is shown in the dagger scene when he sees a dagger that isn't actually there. "or art thou but /A dagger of the mind , a false creation.(2.1.37-38)Macbeth is mad because he is seeing false image wishing there was a real dagger. This is why Macbeth is getting mad because he hallucinates. I can understand why Macbeth would be getting mad because it would be very frustrating to see things that isn't actually there.
