Does anyone know what the moral of My Neighbor Totoro was?

If that あなた have enough belief, anything can happen...

Believe in dust bunnies and good things will happen.
LOL

I think the moral is to believe in what あなた like and it may come true... But, believe in yourself, and あなた can do anything あなた put your mind to.

So the real morale of the story is respect- Nature, the elderly, strangers, family, and for one's self. This is shown all throughout the movie. When あなた respect people, they will treat あなた well & will comfort あなた when you're down. Even if あなた don't want to like someone, あなた should still be kind. And finally, when あなた treat nature with respect, it will respect あなた back.
