Has anyone seen or can remember a Scifi horror from that era (not sure exactly when, could have been '70s or early 80s) about a remote space station. It's a survival horror where the space station's inhabitants are being picked off one by one as they wait to be picked up. There's footage from the alien's perspective as it watches them. The alien leaves what appears to be rocks in the scooped out stomachs of it's victims.
At the end the surviving pair (man and woman) fly off, and then it shows a view of their hold where all the bodies were kept under tarpaulins. Then the tarpaulins start beating.
Never been able to figure out what the movie was. I crept into the living room and watched it from behind the couch when I was three or four and paid for it with nightmares for about a week.
I'd love to watch it again and see how soft I was.
