Hi. I am new to this forum and to the idea of Feng Shui. And TBH, the more I read about it, the more confused I am. It just seems that there is no good bed placement in my bedroom. The room is pretty small and narrow, the window is more or less in the middle of the narrower wall and it's facing southeast. The door is placed opposite to the window, closer to the right side of the room. Also my Gua number is seven, so my head bed should be facing southwest but then I would be sleeping right between the window and the door... I just can't figure out what would be best in my case. Please help.
