Even a perfectly fine suburban tract home and suddenly seem like the Munster's house of weird when unexplained things begin to happen, like cabinets opening and closing on their own, shadows walking the hallways, or voices whispering in an empty room.
Methods for getting rid of such energy vary greatly and most depend a great deal on what you personally believe would be efficacious because your very confidence manifests results.
Here's some things to try -
Methods vary, but I like to light the stick near the front door, blow on it gently to get embers to burn, hold the shell beneath it to catch ashes. Work your way clockwise around your house, being sure to move over areas where energy can trap like dark corners, cluttered areas, and when you get back to the front door again, I usually let it sit in the house a while and then open doors and windows to air the house out after. This is said to be mirrored after customs of native people and even religions, like Catholicism, that utilize incense to ward off bad energy.
Music is another tool that seems to show some good effect. Positive, upbeat music or even music (like above) that is designed to scare off negative energy. Play it a few hours a day in areas that feel kind of dark.
Begin to load it up with things that are positive for you - religious texts, symbols, plants, seashells, crystals, photos of family, figurines of angels, holy water, family heirlooms, whatever it is that calls to you with positive feelings and a sense of gathering all the best elements together. It is a powerful tool and a good one for your own health.
