Key to REM Sleep?

[ecoli]

They say if you get a quick sleep and wake up before you go into REM, say 15 min. or so, then you feel more refreshed. any truth?

[Peels]

what is the difference between REM and normal sleep.... like i know what REM is, but say when you say "im tired i need to sleep" if person A had 5 hours REM sleep only and person B had 5 hours or non-REM sleep... when they woke up how would they feel in comparison to each other?

Here is the answer to your question (only a theory, right or not, you judge it): the non-REM stage is responsible for the processing of the declarative memory, and the REM stage is responsible for the processing procedural memory.

 

I found it from this paper:

So, I guess, both A and B will feel tired in someway.
