Perhaps, than, you can tell the the essential difference, in that regard, between Berkeley's conjecture that the universe was imagined up by someone, vs. the conjecture that the universe was imagined up by God.
Surely, you don't take Berkeley seriously, do you? If the universe is an illusion, the Berkeley's very thoughts are illusions as well and should be ignored. Taking it one step further, I would wager that Berkeley looked both ways before he crossed the street, lest he be creamed by that illusory Mack truck.
