In the early stages of Alzheimer’s, Beatriz sat at a park with her grown daughter but grew paranoid when she thought her daughter had taken her purse. In a middle stage of the disease, she sat in her living room, but a roar filled the air and the shadow of a man jerked violently against the wall. She cried out for help. The roar turned out to be the noise from a fan, and the menacing shadow disappeared once her daughter opened the windows, letting light fill the room.
