Interior designers use mirrors to increase the sense of depth, light and space in a home. However, if placed carelessly, they may cause more harm than good.
While full-length mirrors can be placed in the entrance hall of an apartment, make sure they are not directly opposite the front door, so you don't see your reflection when you enter the house. They should not be on the wall that is immediately diagonal to the front door. Positive energy, including wealth energy, could be reflected away from your home. Mirrors should not be directly opposite the doorways to rooms such as the bedroom or study.
You should also be aware of the positioning of large mirrors in the dining room. Try to ensure that you do not sit with your back to a mirror or have parts of your body reflected in a mirror when dining. This may cause arguments at mealtimes.
Filling an entire wall with a mirror to fill in a 'missing sector' is also ineffective. This virtual approach may create problems because being reflected in a large mirror for any length of time will make a person feel uncomfortable.
