"The Facts in the Case of M. Valdemar" is a short story by the American author Edgar Allan Poe about a mesmerist who puts a man in a suspended hypnotic state at the moment of death.

Valdemar is quickly mesmerized just as both physicians return and serve as additional witnesses. In a trance, he reports first that he is dying and then that he is dead. The narrator leaves him in a mesmeric state for seven months and checks on him daily with the help of physicians and friends. Meanwhile, Valdemar is without pulse, heartbeat, or perceptible breathing, and his skin is cold and pale. Finally, the narrator makes attempts to awaken Valdemar by asking questions that are answered with difficulty, as Valdemar's voice emanates from his throat and lolling tongue, but his lips and jaws are frozen in death. In between trance and wakefulness, Valdemar begs the narrator to put
