While the thieves will be awake and well in their game, I will be drowsy and insecure. Therefore I would never attempt to attack with a weapon that might be used against me, let alone store one near my bed. What I would do is purposly make just a little noise that might imply that someone is awake, but not for sure, thus giving the thieves time to escape on their own terms. If they're too close for such comfort, but still doesn't see me, I might attempt to flee my home should it be possible. If they're right next to me, and I don't panic, I'll pretend to sleep. If they're right next to me and I do panic, I will be at their mercy, and only engage if engaged upon. I would call the police only when I know for sure that they're out of the house. My game is to not provoke someone at an advantage, that would be the same as mashing in a fighting game - senseless and dangerous. What I would fear the most in this situation is thieves intoxicated by drugs, which will usually be the case with amateur thieves.
