Nightmare Fuel / Stay Out of the Basement

• The whole plot. A botanist is doing strange experiments in his basement, and wants to keep out his kids. However, he starts to act strangely, growing more and more distant. Than the kids discover that their father is turning into some kind of plant creature that bleeds chlorophyll and has leaves in place of hair. And later they see that his plants have grown human features, like writhing arms and screaming faces.
• Just imagine the story from Brewer's perspective. You're tied up in a closet by something you created, something that near flawlessly resembles you but is far from human that's living your life, and you're helpless while he plans to do god knows what to your family...
• The clone of the father gets chopped in fucking half.
