The sleeping position which supports you the most can be calculated by your KUA number. Sleeping with your head towards your personal health or success direction is the best position. During the sleep the new and positive energy enters your body through the crown-chakra, so it is important that your head points into these directions to receive the most benefit out of your auspicious directions.
If you are looking for a husband or wife to step into your life or you want to conceive, you can sleep towards your romance direction.

Some important points also have to be considered when setting up your bedroom, as there are: Don't sleep with your feet pointing towards the door, this is called the "coffin position", because you only leave the room in this position, when you are carried out in a coffin.
Don't have mirrors in the bedroom especially opposite the bed, it  can disturb your sleep; if so: cover it overnight with a cloth.
Don't have any water feature (a fountain or a picture of the sea) in your bedroom, as it symbolizes financial loss and as it can create problems in the relationship ... including lack of passion, because the water cools down the fire.
