Fringe Season 1 Episode 17 Bad Dreams

Olivia starts seeing things in her dreams, and then hallucinates about them when she's awake. When multiple people in different cities also start having similar dreams, it's revealed that a group of people were experimented on as children and given telepathic abilities, but the experiments went wrong and they were left traumatized. One of the subjects, Nick Lane, is still alive and using his abilities to manipulate others into doing his bidding. As Olivia investigates, she begins to confront her own traumatic past and the memories she's been repressing.
