I gotta tell ya, this 'red door' thing is freaking me out. I keep thinking of the folktale, "Bluebeard". Familiar with that one?!

Basically a chick marries a rich dude, and he leaves her at home, telling her she can go anywhere EXCEPT the room at the end of the hall. Eventually, curiosity gets the better of her and she goes in... only to see the dead bodies of all the former wives of Bluebeard hanging on hooks and shit! I'm telling ya, Gloria is the female Bluebeard!!
