Okey..
For my bedroom; you go into it, and by looking to the right, that wall (the door is on the same wall) face east, having the picture of Lin.
The house is made like this, not so far away from being in exact symmetry to actual East, North, West and South.
This is how I understand it. My relationship direction is SW, I believe I can put a picture of a girl or something in the SW corner of my room then.
I think it`s as easy as this, if not I`ll learn more on disc 3 and further
