Hollis's Classroom is the tutorial level for the Mental Connection PSI Power. Nagged by Lizzie and Norma, you make a connection in her mind to allow the Interns to go on the dangerous Lucktopus Casino mission. If you were unable to acquire everything here your first time, don't worry, as after the mission ends, you'll have access to the Brain Tumbler, which opens up the Collective Unconscious to return to areas.
