well i heard uberman sleep schedule is exhausting for the first few weeks. and when you are exhausted you are more likely to get sleep paralysis when resting. sleep paralysis is a useful place to achieve a WILD. Although i've never experienced SP no matter how exhausted I've been. The uberman sleep schedule is quite difficult to manage both because of inconvenience and because it is physically demanding. i would also like to know if any people who have done this sleep schedule have remembered dreams or achieved lucidity from their 20 minute naps.
