Insidious is a 2011 supernatural horror film directed by James Wan. It tells the story of the Lambert family who move into a new home. Their son Dalton falls into a coma after exploring the attic. His mother Renai believes something strange is happening in the house as doors open on their own and she sees a frightening apparition. They hire a psychic who explains that Dalton's spirit is lost in a realm called The Further where entities try to possess his empty body. With the psychic's help, Dalton's father Josh must enter The Further to rescue Dalton before a demon uses his body to harm others. The film relies on building atmosphere and tension rather than jump scares to create a creepy impression.
