The furnishings of a house can symbolize the elements of the dreamer's character. Therefore, if you buy something new or are renovating something, surely the same process is happening in your life; perhaps your personality and mind are developing, making room for new actions and attitudes. To buy furniture that is too heavy and difficult to move could represent that you are carrying unnecessary responsibility. Furniture also reflects a specific part of your home. Each one has a function and meaning, so you should interpret them separately.
