Stars cannot shine without darkness ~ Just as we cannot function without sleep
Sleeping is very good for you as you know, but did you realise that an alarm clock isn't that good for us?
In traditional cultures you never woke a soothsayer. Waking them suddenly from their dreaming was dangerous to their essence. Not giving them time to collect all of their soul fragments from beyond the veil.
Maybe this is one reason why in our modern world there is so much modern day stress and mental health disorders.
Ideally, sleep with the curtains slightly apart so you return from dreamland gradually as the dawn approaches and light returns.
Yes,I know what you are thinking.... weekends only then! (lol)
