Van Winkle's story, which is similar to many stories through the centuries about people who sleep for decades or centuries, said he was asleep under supernatural or magical means.

Hypnos and Thantos (god of Death) were brothers in some tellings of Greek mythology and the Prophet Muhammed is recorded as having said "sleep is the brother of death" . This should not be taken as disparaging of sleep or depressing in any way, but a recognition that since time immemorial people noticed the similarities in external appearance among the two states. Poets have long used "sleep" to signify death. Hamlet used it in that way when he said "To sleep—perchance to dream". The Jewish Kabbalah posits that the soul paritally leaves the body during sleep.

The fourth state is turiya, pure consciousness, and during deep sleep we experience a taste ot turiya, which is pure bliss, which is why we find deep sleep so refreshing. Even without the help of modern science, the ancient Hindus knew deep sleep was more refreshing than dreaming, as entertaining and fun as dreams can be.

There are also depictions of good strategies, like daytime napping.
