What are the names of these two old movies?

One movie is set in space on a spaceship. Its more about this girl who has a lot of weird supernatural kind of dreams. One dream as far as i remember, shes alone in some dark area and theres this guy talking to her. He slowly comes behind her and seduces her taking control or possessing her. She closes her eyes and then either she or he slips off the strap of her dress making her naked. Then he cups one of her from behind. The other movie is about this married women with short blonde hair with kids. She sleeps and does it with several other guys commiting adultery behind her husbands back. One scene where in she goes on a business trip with her bos who is an old guy. they stay at some hotel or her bosses. Later at night they have a drink, talk a bit and her boss suddenly starts unoning her shirt or blouse which she also lets him do so as she kind of likes it. And then they do it on the bed. After that she does it with almost every other guy she meets. Please help me. Ive wanted to see these movie again pretty badly. Sadly I don't have their names.
