Jules Verne: Twenty Thousand Leagues Under the Seas

FIRST PART CHAPTER 23: "Aegri Somnia" (continued)

Just then the luminous globe lighting our cell went out, leaving us in profound darkness. Ned Land soon dozed off, and to my astonishment, Conseil also fell into a heavy slumber. I was wondering what could have caused this urgent need for sleep, when I felt a dense torpor saturate my brain. I tried to keep my eyes open, but they closed in spite of me. I was in the grip of anguished hallucinations. Obviously some sleep-inducing substance had been laced into the food we'd just eaten! So imprisonment wasn't enough to conceal Captain Nemo's plans from us-- sleep was needed as well!

Then I heard the hatches close. The sea's undulations, which had been creating a gentle rocking motion, now ceased. Had the Nautilus left the surface of the ocean? Was it reentering the motionless strata deep in the sea?

I tried to fight off this drowsiness. It was impossible. My breathing grew weaker. I felt a mortal chill freeze my dull, nearly paralyzed limbs. Like little domes of lead, my lids fell over my eyes. I couldn't raise them. A morbid sleep, full of hallucinations, seized my whole being. Then the visions disappeared and left me in utter oblivion.
