My Neighbor Totoro
The Death God
This one is a bit dark, and apparently it's widespread enough that Studio Ghibli officially denied that the theory carried any weight whatsoever.
Here's the theory as told by tophat duck in the reddit thread:
The rumor says that Totoro is the God of Death, so the persons that can see Totoro are actually close to death, or already dead. What that means for the story is that when Mei goes missing and a sandal is found in the pond, Mei actually drowned. When Satsuki is asked about the sandal she cannot face the truth and lies about it not being Mei's sandal. So Satsuki goes on a desperate search for Totoro, calling for him and actually opens up the door the realm of the dead herself.
Pretty dark right? Some people say that the story parallels an actual murder case in Japan.
Some people say that if you go in the woods near make out point you might find Totoro and if you check the side of your car later there'll be a bloody hook!
