Hello there, there’s a movie I saw around mid 90s but could have been a late 80s flick. I’m willing to believe it was produced by HBO. Anyways, the only scene I can remember was a dinner between a man and woman, the man excuses himself to the bathroom because he’s been feeling ill. If i remember correctly the man and some friends his were conducting witchcraft rituals in a yard or something to that effect nights prior. He either transforms into a monster or one shows up, I just remember the monster slamming through the stalls and a wall that looks like granite. I think either himself or the woman was wearing purple either as a shirt or dress. Small tibits is all I have of this movie I just remember I was around ten years old and it scared the shit out of me.
