For many centuries the organized, civilized society we created has imposed a structure upon us that we took to like a fish to water. We thrived in it, counted on it and came to believe it's Life As It Should Be. But...
It's an unnatural, imposed structure, borne of something other than the flow of our inherent nature. It's a distortion of life's natural rhythms. And it's way is to compete with nature, not cooperate or co-exist in harmony with it. This contrary way was fine for a long time. But...
These are new times. Calling on all of us to stretch ourselves to new limits, lift and dispel illusions that serve small ideas. And learn to trust that there is something greater than our minds governing the path our lives take, serving a much grander design than we can conceive. We're loathe to trust, but it's become time that we must.
Some of us, myself included, have spent decades being awake in this world only half the time, and the other half... well, let's just say not here. I have slept 10 to 12 hours most of my adult life, and actually a lot of my early childhood as well. I have also tended to sleep mostly during the day, cycling around the months with the moon, not the sun. I found I had about 6 days in a week, not 7. And each day's hours, of course, were longer.
My way has been necessary for me. We are not homogenous blobs of one thought. We are each unique and have our own unique place in the All, harmonized in ways we cannot perceive from here. We each have needs that our minds cannot predict, manage or even fathom. As life would have it, for the last two months I have rarely slept at all, and when I do it is for short stints, 2 or 3 hours, and then I'm up for long stretches again. This change was natural.
Trusting this shift, too, as I had the old way, has allowed me entrance into new thought patterns, new understandings of the human body and mind, the capabilities that have lain dormant for a very long time... it has opened me to many new things.
Perhaps a different approach to your situation would help? Rather than seeing it as a problem, perhaps you can embrace it as part of your nature or natural needs for the time being, and ask to be let in on why from within?
A thought, anyway. Difficult to do in this world of obligations and schedules, I know only too well.
Best to you with this!!
