As a kid in the early 70s I saw a movie where women were mass hypnotized and abducted by some sort of alien group or spacecraft. I remember they all walked as if automatons towards the alien lair/spacecraft (I don't remember which is seemed sort of cave like). Inside the cave/spaceship they lay down on a bed/platform and down went a sheet, when it came up they were gone. Anyone remember this?
You could take a look at Frankenstein Meets the Space Monster. There are a few scenes kind of like that.
If not FRANKENSTEIN MEETS the SPACE MONSTER...perhaps MARS NEEDS WOMEN (1967)?
