Now researchers suspect that dreams are part of the mind's emotional thermostat, 31 moods while the brain is 'off-line'. And one leading authority says that these 32 powerful mental events can be not only harnessed but actually brought under conscious control, to help us sleep and feel better, 'It's your dream,' says Rosalind Cartwright, chair of 33 at Chicago's Medical Centre. 'If you don't like it, change it.' The 34 between dreams and emotions show up among the patients in Cartwright's clinic. Most people seem to have more bad dreams early in the night, progressing toward happier ones before 35 , suggesting that they are working through 36 feelings generated during the day.
