All I remember is the end where a woman is trapped in a room with a creature in a bed. The covers come down revealing a horrific slimy (green?) thing in a bed as she screams. There's a man outside the room who has locked the woman inside. Maybe she's getting what she deserves? That's all I can remember. Help please!
Could it be the tentacled beast in the insane POSSESSION (1981)? http://www.imdb.com/title/tt0082933/?ref_=fn_al_tt_5 (http://www.imdb.com/title/tt0082933/?ref_=fn_al_tt_5)

No, it's not Possession but that's a logical suggestion, thanks! Love that movie, and was lucky enough to pick up the Anchor Bay DVD double feature with Shock (AKA Beyond The Door 2) before it went out of print. I'm a huge horror buff, but this one has alluded me for over 20 years!
Also, one thing I definitely remember about the creature is that it was humanoid.
There is a scene in TerrorVision (1986) that is similar, though not a perfect match.

I was so excited about the release of Terror Vision on Bluray by Scream Factory along with The Video Dead, but alas, it is not the movie I am searching for. I never realized the punk girl in Terror Vision was one of the princesses in 'Bill & Ted's Excellent Adventure', and O.D. was the Werewolf in 'The Monster Squad'! God bless Empire Pictures.
Kind of a long shot, but maybe The Stuff?

No, it is not Larry Cohen's bizarre schlock masterpiece, "The Stuff". What an incredibly fun and weird movie though. I quote Michael Moriarty's character often with friends. "Sometimes you just gotta eat shaving cream!" and "Hey... you're Chocolate Chip Charlie!". I love that s**t!
