To be conscious of waste may mean that we are becoming aware of problems beyond our own small concerns and becoming aware of global issues. Equally, our spiritual energy may have calls upon it of which we are not consciously aware. If we are being wasteful in dreams we need to reassess how we are running our lives. We may be giving too much in relationships, or putting too much effort into trying to make things happen. Waste in dreams signifies matter or information we no longer need. It can now be discarded. Often the colour will have significance. Waste can also suggest a misuse of resources we may initially be using too much energy on a particular project.
