Hahaha, seems like you actually like fight sleep as a toddler. And as you say: "You enjoy putting your mind under some level of stress"
But... just stop there a bit and ask you why?
¿Why insist in putting your mind under some level of stress? ¿For what specifically?
We are talking here about sleep and rest well every time when you actually know that you need it.
So, why not switch your daily dosage of stress for a higher dose of relax, rest and sleep whenever you have the chance just as a test?
Stress always will have the formidable mania of getting to you if you don't even look for it.
¿So why bother looking for it?
And regardless of the eventual results to which this new experiment leads you. Take into account that there aren't and never will be anyone to blame for anything. Absolutely no one!!
Put your fate where it should be put. And wait patiently for the good results without having to force them. Perhaps it is precisely in the dream world where you will finally find the peace and inspiration to move forward without stress. Just dare to enter into the oneiric world more often. :)
