Lisa is an ordinary woman who is overweight and has a gentle personality; she went on vacation to a forest villa with her husband Mark and her best friend Mary. Before leaving, she had a terrifying nightmare in which she was chased by a giant snake in a storm, and Mark and Mary pushed her into the snake’s mouth in order to save themselves. Upon waking up, Lisa was horrified to find that the forest, the villa, and even the generator explosion in reality matched exactly what she had seen in her dream. She tried to warn everyone frantically, but everyone thought she was crazy.
