huh?

A huge stone square, with a sussuration of voices orbiting it. The voices almost have form, like characters from an ancient text. I can't tell if they're talking in english or not, they're too low for me to understand. If I try hard, I catch pieces of what they are saying... but the meaning seems to slip through my fingers. Behind this all a louder, deeper voice rumbles and I cannot understand it at all, but I get the feeling it is talking to me and that I *should* understand it.

What the heck is that about??? And why does it pop into my head when I start praying?
