I know, it looks stupid, but there are upsides and downsides to this. Lemme explain.
Upsides
Ability to sneak up on enemies and take them out easily.
Undetected passage through areas you want to skip.
(Add upsides i've missed here)
Downsides
Enemies regain HP while asleep (the description of sleep status says they will)
Once you've hit an enemy, if they land a successful hit back, enemies within a small radius will be woken up.
Accidentally touching an enemy wakes them up.
Possibly long waiting time if planning on undetection/assassination.
(Add downsides i've missed here)
Discuss.
(This idea was originally thought by DrLequack, but he didn't post it.)
Oh goodie, instead of playing a fun hack'n'slash dungeon crawler, we could hang around on levels for a quarter hour so we can get cheap shots in! Fantastic.
COME ON.
