The last person who told me that he sometimes remained conscious for the entire night, he subsequently developed narcolepsy. I don’t think that clinical narcolepsy is a natural category, but a better one is having little or no sleep other than REM. In some people this eventually causes “excessive daytime sleepiness” and is diagnosed as narcolepsy. But most people with almost all REM sleep forget their dreams normally. If you do go directly into REM, you may find short naps very effective.
