Kiana Aran, a bioengineer from the US, embarked on a five-day darkness retreat in Poland, aiming to study the physiological effects of sensory deprivation. Initially, she found the experience calming, but as time passed, she struggled with disorientation and vivid hallucinations, including visions of her family. Experts, like neuroscientist Susannah Tye, note the lack of extensive research on the psychological impacts of such retreats, warning that they can be psychologically taxing. Despite these challenges, Aran's experience led to a notable increase in her compassion, reshaping her perspective on life and the importance of human connections. She concluded that the scientific work she was engaged in felt less meaningful without the presence of others. This retreat reflects a growing trend among individuals seeking self-discovery through sensory deprivation, although it raises questions about the balance between physical health and mental well-being.
