Black and white together indicates you have a tendency to see life or the subject matter of the dream in black and white terms. This comes across as being intolerant or extremist. You see others are either with you or against you. There is no neutral position allowed. You need to be more tolerant. Another difficulty with being black and white about things is that you judge things as being either in the right or wrong camp. If presented with a third option it must also fit into the right or wrong camp but only one idea can fit into the right one. In order to open your mind to something new, you have to first manage to move the current right idea into the wrong camp and that’s a big task to ask. If you allow for more than just right and wrong you can have many shades in-between. Then you can have something that is almost right. Not being able to eliminate concepts that are holding you back, eventually leads the body into not being able to eliminate waste matter efficiently and manifests as a slow moving colon along with the issues that can go along with that.
Black on its own indicates negativity along the lines of fear, anxiety, resentment, hatred or guilt. A black stain, for example, would indicate guilt. When mixed with other colors, black adds a negative aspect to their meaning.
