I do not believe that a dream should necessarily be taken for reality, or reality for madness.
“Indeed, strictly speaking, it is useless to attempt to express the nature of a thing abstractedly. Effects we can perceive, and a complete history of those effects would, in fact, sufficiently define the nature of the thing itself. We should try in vain to describe a man’s character, but let his acts be collected and an idea of the character will be presented to us.”
Johann Wolfgang von Goethe | Theory of Colours
