Aloha rattler14,
The Bed's facing direction is measured from the footboard as described in the Essentials booklet. That part doesn't rely on where in the room it's located. It could be in the East quadrant of the room and still be a North facing bed.
When putting out your activation cards, she's having you stand in the middle of the room with the compass to figure where the directions lie in that room. You then formulate and place your activations and cards based on that as in Essentials P.14.
Much Love, Shawn
