A lot of spooky things jump out at people in the latest trailer for Insidious: Chapter 3. Though it's the series' third installment, Chapter 3 is actually a prequel to the prior two films. We're hoping it takes after the much creepier original. A prequel set before the haunting of the Lambert family that reveals how gifted psychic Elise Rainier reluctantly agrees to use her ability to contact the dead in order to help a teenage girl who has been targeted by a dangerous supernatural entity. Chapter 3 is out on 5 June 2015.
