Reborn as an ant

My eight year-old had a dream where he lived to one hundred years old and then died and came back two days later as an ant who only lived for 30 days because some kid from his class stepped on him, a kid who he has seen step on ants before.

I asked if he had been taught about Eastern religion, "Have they taught you about Chinese or Indian religion?" and he said no, so this is rather interesting on a many levels.
