Lina’s investigation took her to an ancient abandoned building, a large and decrepit structure that had once housed a psychological research institute. The façade, now covered in cracks and wild vegetation, was adorned with broken windows and rusty bars, giving the entire building a sinister appearance. Her sense of unease grew as Lina delved deeper into the building. Every door she opened, every room she inspected seemed to reveal a piece of a disturbing puzzle, a fragment of a dark past that had left an indelible mark on the walls and the minds of those who had worked there.

In a dark corner of the building, Lina found a series of documents and recordings scattered on an old table, protected by a broken glass case. These documents revealed the clandestine nature of the experiments: studies on mental manipulation techniques, induction of extreme fear and stress states, and methods to alter the perception of reality. The notes were written in a trembling hand and contained graphs and diagrams detailing the progress and failures of the experiments.

The studies, once considered innovative, had been twisted into malevolent practices designed to explore the limits of fear and mental control. Lina found disturbing evidence that Dr. Hayes had participated in these experiments, contributing to turning scientific theories into unimaginable atrocities. Each new find confirmed the connection between the horror she had uncovered and Dr. Hayes’s role in this perverse evolution of psychological research.
