There are many kinds of mass or shared dreams. For now, we will be concerned with the mass dreams that have an almost universal nature; that is, dreams that are shared at one time or another by the majority of living persons on our planet.
This particular kind of dream is concerned with working out certain problems concerning physical reality. The dreams usually are not precognitive, although they might appear to be, since many of the dream events will later occur. They are not precognitive, however, because in a larger measure they bring about or cause the later events.
They occur, comparatively speaking, just above that layer which Jung refers to as the collective unconscious. If you could tune into these dreams, you would have a good idea of the main events of the future because you would see them being born. They are concerned with significant events, that affect many countries. They represent deep intents, wishes and purposes.At times thay have immense power to bring about world-shaking changes of beneficial or destructive nature.
One individual is more important that you have ever dreamed, however, for the intensity and intent are important. One man/woman passionately willing good or evil can overbalance literally a hundred men/women. And in the dream state, also, leaders can be and make themselves known. The people already know them in mass dreams before they are recognized in physical reality.
