Nobody had ever been arrested yet on this earth on account of over-dreaming! It therefore means as long as you can dream, you have neither offended the monarchs nor the Pope!
If dreaming had been a crime, the world would have been the same way it was few minutes after creation; no castles and no gadgets would have been in existence if it were so. All the past and present heroes we see or hear of who have contributed to make the earth a place of comfort would have spent the rest of their days in jail if dreaming were to be an evil act. You are safe to dream!
“Man alone has the power to transform his thoughts into physical reality; man alone, can dream and make his dreams come true”- Napoleon Hill
