This paper argues for a novel way of thinking about hallucinations as intensified forms of mind-wandering. Starting from the observation that hallucinations are associated with hyperactive sensory areas underlying the content of hallucinatory experiences and a confusion with regard to the reality of the source of these experiences, the paper first reviews the different factors that might contribute to the impairment of reality monitoring. The paper then focuses on the sensory characteristics determining the vividness of an experience, reviews their relationship to the sensory hyperactivity observed in hallucinations, and investigates under what circumstances they can drive reality judgements. Finally, based on these considerations, the paper presents its main proposal according to which hallucinations are intensified forms of mind-wandering that are amplified along their sensory characteristics, and sketches a possible model of what factors might determine if an internally and involuntarily generated perceptual representation is experienced as a hallucination or as an instance of mind-wandering.

本文提出了一种新的思考方式，将幻觉视为强化的走神形式。从观察到幻觉与幻觉体验内容背后的过度活跃的感觉区域相关，以及对这些体验来源的真实性的混淆，本文首先回顾了可能导致现实监测受损的不同因素。然后，本文着重于决定体验生动程度的感官特征，回顾它们与幻觉中观察到的感官过度活跃的关系，并调查在什么情况下它们可以驱动现实判断。最后，基于这些考虑，
