There is a movie that I am trying to look for and the scene that I remember most was a scene where a teenage girl was taking a bath in a old bathtub without a showerhead and what looked like to be octopus tentacles coming from the drain and grabbing the girl and attempting to pull her down the drain and it ended up being a dream when she woke up.
I don't know if it would be consider sci-fi or fantasy, but I hope that it is and that I can be able to get this question answered like any question I ask, if I can.
