The spells we're talking about usually have no saving throw, cause they must be put on a willing target, anyway. The matter of sleeping creatures is that they cannot choose, so either they're all affected without getting a saving throw, or they all get a saving throw against the effect (even though the spell doesn't grant one). The thing is: how will you distinguish between friendly "willing" characters or unfriendly ones? Will an unconscious friend be teleportet with you, the unconscious enemy won't?
