Like facing the bed so you see the door when you sleep, etc. (Gives people the willies, otherwise).

Willies hell, it just guarantees a clear shot. Don't want to get the powder burns on the missus when a bad guy comes a calling.

No, you have it reversed. You don't want to NOT be facing the door(feet facing the door is best, but sideways is OK). Read the post again.
