Seriously, Paul .... I have this rough theory which I'm working out in my own head. Essentially, even thoughts which are "bizarre", "fantastical", "wildly out-of-this-world" etc are still thoughts.
So they MUST have some effect on reality (I mean the more observable, objective kind of reality).
Where can we go to observe these effects? My theory is that these effects manifest in areas such as science fiction, art, movies and so on.
To give you an example, JR Tolkien writes a book "Lord of the Rings". Millions of people read it. It is a fascinating book to them, so they think a lot about it. They know it's fantasy, but it's still fun and absorbing, so they think a lot about the book. And the book has been read and well-loved for decades.
So obviously that's a lot of thoughts about hobbits, wizards and so on ...
What effect did those thoughts have on observable reality?
I would say - the partial effect, at least, is this - the thoughts eventually sparked off a chain of events which led to the making of the movie "Lord of the Rings".
Now you know why in some porn movies, there are some people doing some quite unusual things.
Some people somewhere are obviously manifesting some unusual thoughts about sex.
