The illustration depicts a man sleeping in bed with his mouth open; he wears a nightcap, and only his face is visible above the covers. A miniature sultan, with a dark visage and an immense moustache, sits astride an obese pig which, in turn, stands on the sleeping man's chest. The sultan looks down at the sleeper with a comically crazed expression. The picture is naturally framed by the bed curtains, which are pulled aside. The capital letter "N" is engraved beneath the drawing, followed by the word "Nightmare."3The illustration depicts a man sleeping in bed with his mouth open; he wears a nightcap, and only his face is visible above the covers.
