Dreams and the Multiverse
The Devout were also interpreters of dreams. The reason for their focus on dreams was closely related to their belief in a multitude of universes. They believed that as one sleeps, one's soul migrated to its other bodies in these other universes. As most of these universes ran parallel to our own, the more sense the dream made, the nearer its universe was to our own.
The dreamer carried only fragments of these alternate universes back because they can only be retained in short-term memory; long-term memory, they believed, was physical, while the short-term could be retained in the living soul.
It was important to study the Multiverse for many reasons, not the least of which was prognostication, as some close universes may be ahead of ours in time. Beliefs about prognostication caused an important schism early in the Devout history.
