From Beyond | 1986
Dr. Pretorius and his colleagues are working on an experiment involving stimulation of the pineal gland, which they believe may open the human mind to greater dimensions. The experiment succeeds, but has an unfortunate side-effect, the scientists are instantly attacked by dreadful life forms which were previously floating around them unseen. When one of these kills Dr. Pretorius, his colleague Dr. Tillinghast is suspected and confined to a psychiatric ward when he tries to explain what happened. Only one person, psychologist Dr. McMichaels, believes his story and favors the continuation of the project.
