Human Plants

In a warehouse withboxes of algae-like plants. The plants start moving up and down like lungs breathing. Then I walk around and see other plants have grown into shapes of body parts. I am afraid. I am in a vehicle like a golf cart and trying to escape the plant area. Severalnither small vehicles pin me in. I grab a tree hole digger and go after one of the people. He grabs another lady and shields himself and I swing at her. That's all I remember but it has been a few days now and it's still vivid.
