I think this is from a 1950's B & W sci-fi TV series. I would have seen this on Saturday afternoon television being broadcast out of Roanoke, VA around 1958 or 1959. It predates the *The Twilight Zone* series. I seem to remember two young couples, perhaps staying in the country in a log cabin. An interesting rock or meteorite is on their fireplace mantle; I think one of the four found it. It is speaking telepathically. I believe it may have been holding the two couples captive somehow, as I seem to remember the entire episode was shot in this one cabin room.

I have checked episode guides from sci-fi series of that era with no luck (Science Fiction Theater, One Step Beyond, etc).  I did see a scene from it featured on the old "Dream On" HBO series with Brian Benben back in the '80s, a comedy show which commonly used a myriad of brief, quick outtakes from video archives to illustrate the thoughts of the Brian Benben character in each episode.
