Well, I'm not much into napping, but from what I've read - you usually go straight into REM when napping. I guess this would hold mostly if you had a decent amount of sleep prior to that. For me it, takes way too long to fall asleep to be able to take any advantage of any benefits. There are lots of dreamers that say napping is very conductive for lding. You might want to ask Gab or Scionox regarding their nap routine for more info on how they usually do it.
