I am wanting to know the name of a film where a woman went to sleep at night and there was some kind of bright light in the night. When she woke up the next day all the people had gone.She dove around in a red sports car and met some other people whom she formed a family with.

ALSO

I want to know the title of a film where there is an alien family, their young son comes home to a party to fine his family as aliens. But there bodies aren't normal they are disfigured.

Both are 80's or 90's films

I think The Quiet Earth (1985) is the first one

I don't know the first film but the second one is:-
Society (1989) (Ws) (1992)
Starring: Billy Warlock, Connie Danese Director: Brian Yuzna
Hope this id helpful

It also could be "Night of the Comet" (1984).
IMDb synopsis:
Two high school girls wake up to find that everybody in Los Angeles has been turned to dust by a comet except them, a handsome truckdriver, some zombies and the occupants of a secret underground government installation. / The older sister thinks she's alone except for seeing a zombie-creature until she learns, when she arrives home, that her sister also survived.
