Dave Matthews Band - The Stone Lyrics Meaning

I think The Stone is about Dave or a person feeling guilt for a death, and the stone referring to a gravestone.

Here's what Dave says in the outro of The Stone on 10.8.04-

"Go back in your hole again
Sometimes I'd really like you to throw the dirt on me
Let me sink in there
'Til my eyes disappear
But oh, I pray
I'd like to go outside, I'd like to go somewhere out of there
Nothing but a hole in the dark, baby
You send me again into there, baby
Oh, I pray
Let it all fall out..."

^These lines talk about being buried...
