Thanks for your $0.02. I&#x27;m the author of the piece, and I know what  you are talking about. I tried to cheat sleep for a year by sleeping approx 4.5 hours per day. More here: <a href="http:&#x2F;&#x2F;qz.com&#x2F;430415" rel="nofollow">http:&#x2F;&#x2F;qz.com&#x2F;430415</a> (slept 3.5 hours at night and took 3-4 naps of 20 mins in the day)<p>My experience was the same. I used to fall in REM very quickly, many times in the 20 min naps. Here I say REM but really I mean dreams and I&#x27;m taking dreams to be a proxy for REM.
