It is not a dreamlike state, but the somehow insulated state, that a great musician achieves in a great performance. He's aware of where he is and what he's doing, but his mind is on the playing of his instrument with an internal sense of Tightness-it is not merely mechanical, it is not only spiritual; it is something of both, on a different plane and a more remote one.
As to the aridity you are suffering from, it seems to me our Lord is treating you like someone He considers strong: He wants to test you and see if you love Him as much at times of aridity as when He sends you consolations. I think this is a very great favor for God to show you.
Once you get rid of the idea that you must please other people before you please yourself, and you begin to follow your own instincts-only then can you be successful. You become more satisfied, and when you are, other people tend to be satisfied by what you do.
