Krakatit by Karel Čapek

"Now I've blurted something out! " Prokop realized with the fragment of his brain that was most clear; but otherwise he was completely indifferent on the subject; all he wanted was to sleep, to sleep inordinately. He saw in front of him a sort of Turkey carpet, the pattern of which continually changed. It was nothing important and yet it somehow agitated him. Even in sleep he yearned to meet Plinius again. He tried to rid himself of his image; instead, he saw before him an abominable grinning face, which ground its yellow, rotten teeth until they were crushed, and then spat them out in pieces. He wanted to get away from this picture. The word "fisherman" came into his head, and presto there appeared to him a fisherman sitting above some grey water with a net full of fish. He said to himself "scaffolding," and he actually perceived scaffolding to the last hook and rope. For a long time he amused himself by thinking of words and looking at the pictures which they called up; but then not even by exerting all his powers could he recall a single one. He made the most strenuous efforts to remember at least one word or thing, but in vain; and then through the horror of impotence he came out in a cold sweat. He decided that he must go to work methodically; he must begin from the beginning or he was lost. Luckily he remembered the word "fisherman"; but now there appeared before his eyes an empty petroleum tin. It was horrible. He said to himself "chair," and he saw with astonishing clearness the tarred fence of a factory with a patch of dreary, dusty grass and some rusty hoops. This is insanity, he said to himself with cold clearness; this, gentleman, is typical madness, hyperofabula ugongi dugongi Darwin. This technical term for some unknown reason appeared to him to be excruciatingly funny. He positively gulped with laughter and woke up.

He was covered with sweat and had kicked off his bedclothes. With feverish eyes he watched Thomas, who was moving quickly about the room and throwing a few things into a suitcase; but he did not recognize him. "Listen, listen," he began, "here's a funny thing, listen, wait a moment, you must listen -- " He wanted to tell him as a great joke this extraordinary technical designation, and was already smiling in anticipation; but for the life of him he was unable to recall how exactly it had run. He became annoyed and was silent.
