insanity
An insanity is when someone's thoughts or actions don't make sense, often due to mental health issues.
The word "insanity" is commonly used to describe behaviors that seem crazy or irrational. We might say someone's gone insane if they're doing something completely out of character, like a usually calm person suddenly lashing out at others in public. Insanity can also be used more figuratively to describe situations where logic just doesn't apply - maybe you've been stuck in a difficult situation for so long that it starts to feel insane. In some cases, the word "insane" is used as an adjective to describe something that's utterly ridiculous or absurd.
