The figure stepped forward, revealing themselves to be a tall, imposing man with piercing eyes. He introduced himself as Dr. Alexander Black, a renowned psychologist known for his unorthodox methods.
"I have gathered a group of individuals, each with their own unique psychological profile," Dr. Black explained. "You have been chosen to participate in a series of experiments designed to push the limits of the human mind."
Sarah felt a chill run down her spine as Dr. Black outlined the rules of the experiment. Each participant would be subjected to a series of challenges, designed to test their mental fortitude and resilience. The stakes were high, and the consequences of failure were unknown.
As the first challenge began, Sarah found herself plunged into a world of uncertainty and fear. The room seemed to shift and warp around her, and she struggled to distinguish reality from illusion. The other participants watched on in silence, their eyes filled with a mixture of curiosity and dread.
