The obvious example would be Jesus. Jesus is an object of fascination for me. He's an interesting historical character because we don't know much about him. He seems to be a guy who was in touch with something deeper than most people around him were and someone who was very concerned with trying to communicate that.
Now however, we have contraception and it's mostly reliable so you can have sex without that happening. So then you start vilifying the act of sex itself. I don't think Buddhism has ever done that necessarily, or at least I'm not aware of Buddhism taking the stance that Christianity often has which says that sex itself is a kind of evil act, which is a really weird idea.
So I'm skeptical and cynical about the whole thing and it's only if something seems to be genuine that I would pursue it. That's why I've stuck with Zen for so long and not gone on to some other path with it.
Godzilla also represents the fear of nuclear annihilation, which was something that was big in my mind at the time. It was something that the people of this forthcoming generation haven't had to live with, but people around my age grew up with the idea that we could all be blown up at any minute. That's also what got me into hardcore music.
At times, Zen does get into some Buddhist Cosmology. Nishijima Roshi, my main teacher would talk about that and almost every time immediately say that it was only one way of looking at it. Whenever addressing realms of Heaven or Hell, he'd also address that it was just a psychological state.
Much of the hatred and fear of sexuality found in religions stems from the idea that sex is a thing of the body and that the body must be denied so that the spirit may be elevated. In Buddhism there is no notion that the body is made of inferior matter while the spirit flies free within.
Sanity and enlightenment...I've been reading a new book Dogen's Genjo Koan: Three Commentaries, and it contains a commentary on Genjo Koan by Shunryu Suzuki, the author who wrote Zen Mind, Beginners Mind. He doesn't mention sanity at all but I think that one possible definition of enlightenment would be a kind of profound sanity, where being insane is no longer an option.
There's also something that is often mistaken for enlightenment which is a kind of insanity. Often, people will have some kind of weird experience which is quite abnormal and think, "Oh my God, that's it, I understand everything" because they start seeing things in a very weird way and think that's how enlightened people see things as well.
