The search activity concept proposed a new classification of the types of behavior according to the adaptation to the environment. In this article I have explained the story of the creation of this concept and discuss the probability forecasts of the outcomes of activity in different types of behavior and in REM sleep dreams. The direction of search can be changed if the outcome of activity does not correspond to the forecast. Stereotyped behavior uses habitual skills and algorithms with a definite forecast of the results. Chaotic (panic) behavior does not include monitoring of the results of activity. It determines the unreasonable fluctuations of the direction of activity independent of its outcome without probability forecast. Finally after painful failures it can lead to the renunciation of activity where the forecast of the positive results of activity is on the zero level. In REM sleep dreams subject is separated from the surrounding environment and the “failures” of the virtual activity are not dangerous for the subject. The process of activity by itself is more important than its direction and its outcome. For this reason search activity in dreams imitates chaotic activity in wakefulness however without its negative outcome and after awakening subject is ready to perform normal search activity.
