So it's really open to interpretation, but I felt the plants were feeding off and fueling the protagonists loneliness and this kind of psychic feeding gave them weird vivid dreams while the feelings of isolation and paranoia are what actually give the dreams their substance. Then after feeding off so much loneliness they decide they want to help
But that's just one interpretation. I picked pink for the color of the plants and important things in the dreams because that kind of pink is kind of an alien, out-there color in nature and I didn't really intend for their motives to be fully comprehendable.
