Perhaps people who are unable to sleep sufficiently or at all, are afraid or unprepared, etc., to "face" their sleeping self!
Insomniacs, and even those who are closet insomniacs, namely those who need uppers, caffeine boosts, etc., may be afraid to BE alone, asleep with themselves! What if it could be shown that insomniacs,etc., FEAR sleep because sleep HAS to be PERFORMED alone, instead of as a relationship "sport"?

Spooning and all the other sleeping rituals (bathing before bed, bedclothes preparation, pillow airing, etc., could be seen as sleeping "sport" rules. Even the trend of wearing pajamas or pajama like hipster outfits to work and school may be seen as a sleeping "rule" of dressing for the sleep performance "sport".
Those who have performances for others (i.e., relationships) in place of performances for and with themselves, their valid self, might be expected to have a higher incidence of these sleeping rituals and, as a result instead of having sleep they have sleep rituals, instead of having sleep they have a sleep performance, and, instead of having sleep, sleep HAS them.

Studies show that women, and others who value and view relationships more highly than autonomy, mastery, and purpose(where purpose is viewed as self generated, motivated, validated, instead of other derived)have reported higher rates of insomnia. This could be a function of communication being greater among insomniacs simply because they have more awake time TO COMMUNICATE! lol Perhaps we need to look at insomiacs differently, Perhaps insomiacs cause accidents because they need relationships more than they need and want alone, sleep, "down" time! Perhaps insurance companies need to make sure that their clients are persons in their own right instead of relationship "performers".

Of course we all, to some degree, perform for and with others, but the measure of our alienation from ourself may be the degree to which we TAKE that performance for, and with, others SERIOUSLY. Those who take relationships so seriously, those who are unable or unwilling to see that PERFORMANCE in relationships is paid for with alienation from the emotional integrity of the authentic, autonomous self, may have that self return the (dis) favor with insomnia.

A start to an alternative to insomnia may be to begin to see the rituals surrounding sleep for what they are, namely a hypnotic like tribute to the buying, selling and consuming of sleep performance signifyers. We are so ordered, or we order ourselves to sleep in a bedroom, sleep at night, sleep and even DREAM the "right" way! (I recall telling a relative a dream I had and was told, in all seriousness "You shouln't have a dream like that" lol!) Our sleep or lack of it, is trying to tell us something. Maybe what our sleep, or insomnia, is trying to tell us is that if and when you get, or give yourself enough QUALITY, restorative, rejuvenating sleep (namely when you have a self and PERFORM sleep with and FOR that self) even your dreams will say "Thank You!",
