What does a butterfly landing on a coffin mean?

A butterfly landing on a coffin is "symbolic" of an afterlife. Butterflies start as eggs, then larva or "caterpillars" and then form into pupa which look like little coffins and were once thought to be dead. The emerging butterfly is reborn into a new, beautiful life.

To see a butterfly land on a coffin is thought to mean that the "person" within has been reborn or claims his new life as in an afterlife, casting off his human wrappings.
