There are pretty much only two ways to look at reality. One, matter is all that exists and consciousness is an epiphenomena, i.e. it doesn't exist. (Those who believe in Neo-Darwininian evolution, Evo-Psych, the Dark Triad and other such things are falling into that trap, even if they don't know it.)
The second way is that Mind is that ultimately exists and Matter is created by mind. That's the religious view, in various forms. Philosophically this is known as Idealism, and the totality of reality is known as the Absolute.
I've seen both these views among people. Each believes them because in some way it gives meaning, importance and community to their lives.
There is another, hidden ("occult" actually means "hidden") view and it tends toward the "religious" view (although it many religious people see it as "occult" and evil). I've seen this, too, although it is quite rare. But as society collapses farther and farther, I expect to see more of it.
A part of this "occult" view is that there is a "sex magic." You might want to investigate the life of the demented Aleister Crowley to understand some of it.
Generally it's been the sillier and more adolescent women who believe they're witches, or that astrology is a science, or that they have occult powers. It's one of the reasons if women are allowed to have much influence in religion they'll turn it into some sort of degraded pagan religion.
Yet men fall for it, too, but in their case it does tend to be about gaining control of some sort of Sex Power. Actually, all of these things are not just about importance, meaning and community, but also about having power and control over things and people.
I'll quote from Wikipedia on this (which actually got it right this time): "Sex magic is a term for various types of sexual activity used in magical, ritualistic, or otherwise religious and spiritual pursuits. One practice of sex magic is using the energy of sexual arousal or orgasm with visualization of a desired result. A premise of sex magic is the concept that sexual energy is a potent force that can be harnessed to transcend one's normally perceived reality."
I've seen people try this.
As society and culture collapses farther and farther all kinds of belief-systems will pop up to fill the void - Wicca and Neodruidism, for example.
