Water:  Water is a life force, avoid painting or pictures of water in the bedroom, especially above the bed, the energy of water is above you therefore it signifies discordance with nature.  You could wake up drained of energy, and/or with more conflict in relationships.  Keep water paintings in living room areas. 

Mirrors:  Mirrors double energy and space.  Having mirrors in the bedroom can double energies or stress.  Remember a TV is considered a mirror too.  Cover it up or remove it from the room.  Mirrors are good for hallways. The best place is to place a mirror is an entrance of a business or home.  It promotes active energy.

Sharp edges:   Avoid cactuses, sharp leaved plants because it affects the aura field in the house and increases conflict in the home.  Furniture with curved or round edges create more energy flow.
