You wake to the feel of rain on your skin. In a panic, you jerk to shake it off, but then realize it doesn't burn. It feels nice. Weird. Must have something to do with that weird book. You look around and see that your small room is gone. You're not sure where you are, except that it looks like an old illustration from VR science class. An ancient biome, with tall, rough-surfaced plants, whose limbs end in thousands of tiny green needles.
The needles cover the ground where you lay. You thought they'd hurt, but they just feel soft.
Get up and walk among the plants.
Move to the nearest plant and climb.
