Started taking a supplement called super sleep (100mg -Theanine,15 mg - 5-HTP, 1.5 mg - Melatonin each times 2) 2 nights ago. Resulted in the first time in 2 months not remembering a dream. Will stop tonight and save for days when I can't sleep, need deep sleep, or have lots of time in the morning for deferred REM sleep.

Is anyone able to confirm my understanding of how this work (am browsing Lucid Aids but I'll pose the direct question here also)? These supplements, like alcohol, suppress REM sleep leading to a deeper sleep at the beginning of the night with less REM and resulting in more REM sleep at the end of the night. Is this correct?
