I once had a Ouija board. Never really used it, though. I find the nattering of most living people empty and pointless; I can’t imagine it improving much from beyond the grave. It’s probably all descriptions of endless empty voids and what it’s like to freely watch people as they use the bathroom. Dull as dirt. Speaking of which, there’s probably lots of talk about that, too.
Here’s a poem.
Whispers from the dead
Tongues writhe like feasting maggots
Vomit dirt and rot
