Well I have to disagree with the majority of the voters and say life. In a lucid dream I can wish it and it shall be so. In life I find it exciting to know that I have to work at it. When ever you cheat in at a game it ussally detracts from it. Also there is no danger in my dreams. If I die I can just respawn or resurect myself or what ever. You can't do that in life. You can spend life times in your dreams but you only get one real life.
