Dreams of death signify change in all its forms. You are about to go to a higher level than you have been with your art and these dreams reflect that and the anxioty you're feeling.

But this is a GOOD change and I know you are up to it. If you weren't stressed out about it I would be surprised.

So while they are disconcerning its just your subconcious dealing with it all. You will perservere. :D
