This page is kept for completeness. It describes research conducted before the Quieting, when dreaming was still considered a normal part of sleep.
On 1953-09-04 the journal Science published a two-page note by Eugene Aserinsky and Nathaniel Kleitman describing periods of rapid, jerky eye movements during sleep, accompanied by changes in brain activity. Sleepers woken during these periods reported vivid dreams. It was the first physiological evidence that dreaming has a time, a rhythm, and a signature.
A footnote in the archive record refers to a night observation made at the Konkoly observatory: an astronomer, asleep at the eyepiece, woke and drew a tree he insisted he had seen standing in a square of a city under rain. The drawing survives. The city did not, then, exist.
"The source remembers what the page forgot."

REM periods still occur. Recall does not. Whether the two facts are connected is outside the remit of this service.
