Sleepwalkers (1997)

Short-lived series about a group of dream researchers who use special sleep-beds to electronically send operatives into people's dreams, where they can witness first-hand their subjects' visions and nightmares, and interact with them in an effort to sort them out. They're available for hire by individuals, as well as wider-ranging problems, such as a medical outbreak in a small town. The show was promptly canceled and pulled from TV even before the first season finished airing, so the show's emerging main story arc was left unresolved.
