The article delves into the complex world of sleepwalking, defined as a parasomnia that occurs in the deeper phases of sleep. It describes sleepwalkers' ability to perform various activities while seemingly awake, including walking and speaking without conscious awareness, leaving them in a state of confusion upon awakening. This phenomenon highlights the disruption of restorative sleep processes, such as neurological recovery and stress reduction, which are essential for physical and mental health.

Nicolás Hochman's book, "La parte del sonambulismo," published by Fondo de Cultura Económica, serves as a focal point in this exploration, providing insights into the dual existence of sleepwalkers. The narrative contrasts the mundane realities of daytime life with the surreal experiences that occur during episodes of sleepwalking, portraying the mysterious and often misunderstood nature of this sleeping disorder. Hochman’s narrative brings forth an intimate examination of the psychological and physical ramifications of this condition.

This exploration raises questions about our understanding of consciousness and the various states of being that exist between wakefulness and sleep. In doing so, it encourages a deeper appreciation of the intricacies of human behavior and the fine line that separates normalcy from the extraordinary, as revealed through the literary lens of Hochman’s work.
