Alien Invasion/Abduction Moovie from (probably) 60s

[hotspur]

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)?
