Munch described his inspiration for the work thus:
I was walking along a path with two friends. The sun was setting – suddenly the sky turned blood red. I paused, feeling exhausted, and leaned on the fence – there was blood and tongues of fire above the blue-black fjord and the city. My friends walked on, and I stood there trembling with anxiety – and I sensed an infinite scream passing through nature.

The Scream by Edvard Munch?
Somehow it always reminds me of Franz Kafka’s novel, The Metamorphosis.
