Ghosts ESP - Psychic Trek

Star Trek was one of the first TV shows to deal in concepts of ghosts ESP. Enterprise had a psychic - Vulcan science officer Mr. Spock. Spock, though half human, could mind meld with aliens or sense "danger" when Vulcans were dying. Later on Star Trek: The Next Generation, Counselor Troi was a Betazoid empath. She couldn't mind read, but felt what others felt by a psychic link. Ghosts were in Gene Roddenberry's universe. In "Wolf In The Fold" - a ghost like demon - a serial killer - took over humans and possesed them. Star Trek: TNG had 'Sub Rosa' - where Dr. Beverly Crusher actually fell in love with a "ghost" - or a kind of energy being which manipulated and fed on human emotions
