Fans, a series that may of us "ancient blood" folk remember fondly from the early 1970s is "The Sixth Sense." Gary Collins starred as Dr. Michael Rhodes, an ESP investigator and psychic. Thanks to the kindness of a friend, I just learned that episodes of this series have been screening at least occasionally on the CHILLER network.
Dark Shadows connections include appearances by Dana Elcar (in the episode "Witch, Witch, Burning Bright"--sounds like a certain blonde sorceress known for her evocative cackle!), John Karlen, and Joel Fabiani--there are probably other DS connections if you dig around enough.
The series is moody and slow-paced, sometimes featuring psychedelic camera angles and dream sequences that seem very reminiscent of DS. The episode I saw had the heroine being granted a vision of five widows in long black veils--at least one of the widows was wearing a miniskirt, which again seemed very DS!
