So, here is all I remember… as a very young child (don’t judge), with my parents falling asleep at the drive-in, I would lay in the back window of the car and watch all the horror movies on the other screens. I don’t think i had a radio at that time, so I have no sound context to work off of, but i remember one distinct scene. It is of some sort of party, and I believe it was vampires.

The part that stands out was that they were pouring either wine or blood down the front of nude women, and catching it in a wine glass, handing it out to the party/ritual guests. I think it was a gothic style, but I could be completely wrong due to how long ago it was, and how limited my view was.
