Or maybe 'each to their own'. I've had insomnia for a while so I know how bad it is to go on too little sleep but I also really don't need 8 hours and staying in bed when I'm awake and have stuff to do is something that I find pretty hard to do.

Ah, but do you love sleeping itself, or the context to safe and secure sleep, the luxury of a warm bed and the knowledge you can get the sleep you need, getting up when you like and feel refreshed?

I get that that is what you are saying is a part of the quality of sleep experience, but those qualities are not really about duration, you either have those privileges or you don't. If you are lucky enough to have a biological clock requiring less hours per night to enjoy them fully, that's ok.

I would agree though that to forgo those qualities intentionally over an extended timeframe is a curious choice.

I love dreaming and I think it can be used as a tool to get to know yourself, and even practice skills.

I think some people, specially nowadays, live in a very conceptual world inside their minds, and anything that they don't understand or deem unrelated to it, they compartmentalize as disposable, where in reality they're being a bit childish in how narrow they view the world.
