Well, it's WILDing in WBTB after 5-6 hours of sleep, not after REM, and not for the reason of being more relaxed, but because it's much simplier to reach REM and keep awareness in WBTB than when going to sleep at normal time.

Also please, don't post in threads which haven't seen activity for years, especially when OP wasn't on for years as well, it's considered necroposting. Thanks.
