Here is a story from Robert Moss’s dream circle that illustrates how objects (in this case, dog tags and medals from dead Vietnam soldiers) can retain energy—positive or negative— How to stop dreaming dead men’s dreams I – Dream Gates. Residual energy that doesn’t belong to you or your household can cause nightmares (as they did for Cara in the story) and other feng shui problems within your home. If you’re at all sensitive to energy it can often be confusing to know what feelings belong to you and what you’re picking up from the ethers.
Along with your spring cleaning, it’s a good idea to clear your space of this lingering ch’i energy at least once a week. And if you bring a new object into your home–preowned or antique–smudge it thoroughly to reset the ch’i.
