Toward 100% dream retrieval by rapid-eye-movement sleep awakening: A high-density electroencephalographic study.

This study aims to demonstrate that dream images can be retrieved from virtually all REM episodes across the night in any neurologically healthy individuals and that high-density electroencephalography is superior to the standard polysomnography in identifying sleep events and localizing wave sources. Seven young adults, who rarely recalled their dream experiences, volunteered to attend a screening interview, keep a nightly log, and sleep at the laboratory for 3 consecutive nights. Awakenings were made on the third night, the first 2 nights serving the purpose of adaptation. By utilizing the electroencephalographic system with 256 channels and the awakening protocol that accommodates the normal lengthening REM periods over the night, a very high retrieval rate of REM mentation was obtained—that is, 94.3%.
