The details of the dream can offer more insight into what's really going through your head. The person you imagine passing is especially significant. “You are usually using them to represent a characteristic, or personal quality of your own,” says Ian Wallace, a dream expert and psychologist, in his book The Top 100 Dreams: The Dreams That We All Have and What They Really Mean . “Death of your loved one in your dream indicates that this particular quality that you possess is being transformed in some way. The transformation is often the result of a major change in your waking life where you have to let go of old habits and welcome new ways of doing things.”
