The Cabinet of Dr. Caligari ending explained

What happens

Francis is revealed to be a patient in the asylum, telling his story in its garden. Jane and Cesare are fellow inmates, and the director who looks like Caligari calmly says he now understands Francis's delusion and can cure him.

The last image

The director studies Francis with a calm, kindly look, and the film closes on him, having just promised a cure.

Three readings

1 · Francis is delusionalThe murders and the evil Caligari were a madman's invention, and the director is a caring doctor.

2 · The frame liesFrancis told the truth, and the ending shows an abusive authority declaring him insane to silence him.

3 · Both stay possibleThe film refuses to settle it, so you must decide whom to trust.

What it says

The ending turns the film's fear of authority into a question about who gets to decide what is sane. Whoever holds power tells the story, and a single point of view cannot be trusted. That doubt is why people still argue about it.
