Eureka: Season 2, Episode 6

2 - 6: Noche de Suenos

An epidemic of shared dreaming in Eureka seems amusing, if somewhat embarrassing, until it's discovered that the cause will ultimately prove lethal for everyone in town. They discover that Stark and Allison were trying to be in Kevin's dream (Kevin now has a special connection to the Artifact), but it interferes with a neurologist's neural network of 50 people, who the dreams originate from, and when the dreams occur, a compound builds up in the spinal cord. Three people die because of it, and Carter and Jo are part of the neural network. So Stark's dream-reading device is turned off and Carter, Jo, and the others are cured.
