A house (or an office or a store) is like a sponge. Whatever transpires in your environment is absorbed into the walls, furniture, carpet, ceiling, and objects. Frequently, these negative energies accumulate in the corners and tucked away places. Energy debris can be a result of negative emotions, thoughts, occurrences, and stress that you (your family, your co-workers) have experienced in your space. If you had a negative event happen recently or a lot of sadness or fear, there is a high chance that your space will have absorbed some of that energy. At times — in particular for older houses or houses (and offices) that have been occupied by other people before you — those energies can have accumulated over time and be connected to tragic events that you have no idea about. Without talking about the land itself, that can carry energy from generations before us.
