[tlhIngan Hol] subjects and objects in imperatives

I know that this must be a ridiculous thing to ask, at this point, after having written my brains out in Klingon, but this thing since it came to my mind is killing me. Who the jay' is the subject and object in an imperative??? I say to someone: yIQong! sleep! Who's the subject and who's the object? I say to the judges: yaS tIqIch! condemn the officers! If the subject are the judges, and the object the officers, then what am I? (i.e. the one who gives the command). It seems a ridiculous thing to ask, but it's driving me crazy. ~ Dana'an
