Hi, Mayflowers. No, the bedroom is not a different energy. Personal Best Directions and Space Feng Shui are different. When you activate your Personal Best Directions, no matter if it's in your bedroom - living room - office - wherever, you are placing "personal" items such as a picture of you and your partner in your relationship corner, or your vitamins or health care provider's card in your health direction. No matter what direction it is, N, S, E, W, etc. you will place these items to bring that focus of energy into your life.
When you activate the aspects of Space Feng Shui and the 24 Facets, again in any room, SW for motherhood and romance, E for family, W for communication and children, etc., you are activating those specific aspects and it is totally separate from anything to do with Personal Best Directions. If E is your total loss and you place a plant there to activate family and health you are not activating total loss. In fact, you are doing the opposite. Being sure that your four less good directions are properly feng shui'd for space and time actually negates some of the effects those less good directions have for you. If E is your success direction and you place a plant there that is good but you still need a personal activation for your success there also.
