Assuming that he/she/it is a god with the power to create it's own reality. It much prefers It's dream. In fact It is in love with his dream(s). More so than his reality. Therefore his artistic "genius" is wasted in the reality he creates and seeks refuge in his dreams. Where his artistic "genius" can be fully realized as he can't seem to create it in reality like it is in his head.

I... what?

Correct me if I am wrong but the "godhead" is a sleeping mad god's mind. This godhead is dreaming. This dream is everything that we know of in TES. Anu maybe the current persona doing the dreaming in the godhead.

Literal thinking is bad art.

Yes.
