Consider this quote from Dream guru Jeremy Taylor:

In my experience, all dreams (and particularly nightmares) come in the service of health and wholeness. This means that no dream, no matter how distressing or menacing, ever came to anyone to say, “Nyah, nyah, you’ve got these problems and you can’t do anything about them!” The very fact that a dream is remembered in the first place means that the dreamer actually has at his or her disposal all the courage, creativity, strength, and wisdom necessary to respond creatively and transformatively to even the worst “problem” that the dream presents. (If the dreamer were not in possession of all the energies required for positive, creative, transformative response, the dream would simply not be remembered.) This is true not only at the level of individual, psychospiritual health and wholeness, but at the level of world society, culture, and collective human struggle as well.

Ironically, for this reason I take heart every time I have (or hear about) a dream that involves large, planet-wide problems like destruction of the environment, plague, military conflict, or other massive disruption of society. The fact that we remember such dreams suggests that we are able to respond creatively and effectively to these problems, in the same fashion that dreams addressing seemingly “insoluble” personal problems always indicate our ability to deal with those problems. Nightmares may also provide symbolic suggestions and specific creative inspirations, provided we have the wit and wisdom to pay attention.
