Wierd rp idea involving a mind-controlling plant that produces shapeshifters??

In the dream, I was a female human who was visiting her out-of-town family for summer break from school. At the begining of the dream, she hears a voice tell her something isn't quite right with one of her family members. After a while of socializing with her family, she noticed her cousin was shying to the family office quite often, and was trying to show something to certain members of the family. They kept guiding the others to the back of the house, only to return alone. Sure the members would show up later but again, something didn't seem right with each one. They'd come back a lot quieter and less... characteristic of themselves.

The voice had spoken to her again and said "this isn't a joke. Kill the host and destroy thier communication to regain your kin before you suffer the same fate!" She had no idea what that meant, but she could see whatever it meant, it wasn't a joke. She soon snuck into the families office, tipped off by her cousins initial actions. Inside, she finds stacks upon stacks of freshly printed papers. Most of them had images of a strange carnivorous plant, while some of her family and others with words... orders about which member to... consume!? How to convince them in case they didnt want to follow, and who to take instead if that didn't work. Suddenly, my dream-self knew she was in deep trouble. With a picture of the plant in hand, she leaves the office and ventures to the back of the house where her cousin had been leaving the others. She picks up a knife from the kitchen on her way.

To her surprise, there was nothing out of the ordinary back here, save for some soil near the back door. Stumbling into the back yard, she spots a plant identical to the one in the picture. It's singular large bulb was spread three ways to reveal sharp teeth lining the edges with its sticky lustrous purple saliva. Her brother was hunched over the plants open bulb, head practically resting on the 'flower'. He seemed to be in a trance as he stared down to it. Upon trying to pull her brother away from the plant, it stretches and latches onto the arm in which she had her knife. The brother had already been converted by the plant and sat back as his sister struggled in attempt to get free. The damn thing didn't let go and with every jerk the teeth sank deeper and ripped at her arm. It wasn't long before her cousin, the start of all this comes back and snatches the knife from her hand before helping the plant to clamp to her head, slowly converting her to another pawn of the plant. The dream ended there, so what do you guys think?
