 Some individuals possess the ability to daydream so vividly that they experience a sense of presence in the imagined environment.This experience is reported to be extremely rewarding to the extent that some of those who experience it develop a compulsion to repeat it that is often described as an addiction.The scientific literature suggests that a portion of people with maladaptive daydreaming can spend up to 60% of their waking time daydreaming, and could, therefore, be classified as suffering from a behavioral addiction.Stimuli for maladaptive daydreams range in all kinds of places, and their "symptoms" are also numerous.
