i have accidentally stumbled across a dragon resurecting another (yes i did the quest relating to this).
the dragon flew away and now the grave is still causing the storm and a voice says something along the lines of "speak if you have say of the listening" (probably not exact WTF???)
anyway is there anything i can do and if so, what? ive tried shouts but it just makes the voice say it again.

Try reloading your last auto save?

Some of the ressurections of named dragons can be very bugged, I have found that fast travelling to a location close to the spawning can "fix" some of the problems. Making a save, quitting, and then reloading can also fix the spawning of the dragon.
