From Maupassant's Une Vie

Then she had a nightmare, or was it a nightmare? She was in bed. It was broad daylight, but she could not get up. Why? She did not know. Then she heard a little noise on the floor, a sort of scratching, a rustling, and suddenly a mouse, a little gray mouse, ran quickly across the sheet. Another followed it, then a third, who ran toward her chest with his little, quick scamper. Jeanne was not afraid, and she reached out her hand to catch the animal, but could not catch it. Then other mice, ten, twenty, hundreds, thousands, rose up on all sides of her. They climbed the bedposts, ran up the tapestries, covered the bed completely. And soon they got beneath the covers; Jeanne felt them gliding over her skin, tickling her limbs, running up and down her body. She saw them running from the bottom of the bed to get into her neck under the sheets; and she tried to fight them off, throwing her hands out to try and catch them, but always finding them empty.
