Personal account of four days in a darkness retreat

By the Editorial Team · Saturday, July 25, 2026

A participant completed a four-day retreat of total darkness and sensory deprivation, documenting the physical discomforts and intense psychological effects experienced throughout the 84-hour isolation. The experience revealed both the therapeutic potential and mental difficulties of such retreats, highlighting growing interest in digital detoxes alongside warnings that extreme sensory deprivation may not suit everyone.

A participant in a recent four-day darkness retreat has provided a detailed personal account of the experience, highlighting the physical and psychological challenges of spending several days in complete sensory deprivation. The retreat, conducted in a specially designed room that was entirely dark, aimed to offer participants a break from external stimuli such as light, sound, technology, and social interaction.

The retreat spanned 84 hours during which the participant remained in total darkness, with only two meals a day delivered to the room. Activities were limited to rest, meditation, and minimal movement. The participant reported initial difficulties adjusting to the environment, including challenges with routine tasks such as using the toilet without light and eating in the dark. Without visual cues, eating meals proved to be a slow and disorienting task, and sleep was elusive—more a state of near-sleep than deep rest.

Over the course of the retreat, the participant experienced a range of emotional and psychological responses. Early on, feelings of boredom and loneliness predominated, interrupted by moments of emotional release and introspection. At times, vivid hallucinations appeared in the form of shifting lights and abstract shapes, a phenomenon also reported by others undertaking similar retreats. These hallucinations, described as fleeting and rare, temporarily alleviated the monotony of darkness.

Throughout the experience, the participant reflected on past memories of isolation and insecurity, contrasting the current voluntary solitude with previous periods of involuntary loneliness in childhood and young adulthood. The sensory deprivation prompted a mournful contemplation of lost innocence and familial disconnect, as well as an acute awareness of the absence of familiar domestic sounds such as children playing and family voices.

Experts note that while darkness retreats may offer a unique opportunity for a digital detox and mental reset, they are not universally suitable and can be psychologically taxing. Dr. David Luke, a psychology professor specializing in altered states of consciousness at the University of Greenwich, cautioned that some individuals may find such retreats “challenging” or even “disturbing.” However, the appeal of disconnection from technology and the external world is growing amid increasing concerns about digital dependency and mental wellbeing.

Upon completion of the retreat, the participant described a profound sense of relief and heightened sensory awareness upon re-entering the light. The transition included emotional reconnection with family and a renewed appreciation for everyday experiences, including a return to coffee and music after four days without caffeine or external entertainment. Despite the initial impulse to seek escape, the participant concluded that future breaks might be better served by less extreme measures, suggesting that a walk without digital devices could offer respite without total isolation.

The darkness retreat experience highlighted both the potential benefits and significant challenges of prolonged sensory deprivation, providing insights into human consciousness, the effects of solitude, and the complex relationship with modern technology.
