Found another good (IMO) old movie yesterday, Seance on a Wet Afternoon (1964). Not horror, but psychological dealing with madness concerning a domineering, manipulative unbalanced woman who works at home as a medium and her docile husband. Acting was excellent along with intelligent dialogue. Atmosphere and set decorations added to the story.
@roccobass, after reading your post, I found The Monolith Monsters (1957) on Tubi. Perfect Saturday afternoon viewing, just like when I was a kid when Saturday cartoons were over LOL. A little girl on a field trip just took an alien rock. What could possibly go wrong? LOL
I know. Regarding the little girl, being well behaved and minding mom, (who didn’t want the dirty rock in her clean house), the little girl puts it in a barrel of water! It was all I could do not to scream “Noooooo, don’t do that!”, at the TV!!
