" The general function of dreams is to try to restore our psychological balance by producing dream material that re-establishes, in a subtle way, the total psychic equilibrium. This is what I call the complementary (or compensatory) role of dreams in our psychic make-up. It explains why people who have unrealistic ideas or too high an opinion of themselves, or who make grandiose plans out of proportion to their real capacities, have dreams of flying or falling. The dream compensates for the deficiencies of their personalities, and at the same time it warns them of the dangers in their present course. If the warnings of the dream are disregarded, real accidents may take their place. The victim may fall downstairs or may have a motor accident. "
