Summary

This chapter shows that the study of dreams provides meaningful and valuable information about cognitive and affective processes occurring during sleep. It demonstrates that typical features in large dream samples can be identified using statistical methods and that these features are in good correspondence with known patterns of brain activity during sleep, in particular rapid eye movement (REM) sleep. These analyses are based on the frequency of occurrence and degree of uniformity of dream contents, irrespective of whether the dreams mimicked real-life experiences or were extremely bizarre. The chapter also shows that bizarre but common aspects in dreams have much in common with known neuropsychological syndromes. Integrated approach to sleep and dreaming undoubtedly contribute to redefining the links between brain processes and the varieties of dream experiences, and lead to a more comprehensive model of human brain function during sleep.
