I know there is a custom to sleep or position your bed where your feet are not facing or do not point out the door while in bed. This is due to the fact the dead are carried out feet first.
Now is that the bedroom door? The apartment door? The building door? Because they all are in different directions.
And also is that directly opposite the door or just in the direction of the door? So for example:
X is the bed and door is D , feet are not opposite door but are NE direction – also counts?
