Imagine Herbology class at Hogwarts.
After walking down to the greenhouses, you arrive at the correct one and go inside. The air is warm, damp, and smells fresh and earthy. Looking around, there's a whole lot of green. A small radio is playing peaceful music. A plant that you can't yet identify seems to wave and then stretch towards you.
Professor Longbottom runs into the greenhouse and starts the lesson, and the plant draws back at the sound of his voice. The lesson goes on peacefully, Professor Longbottom explaining how to handle a plant. Nothing goes wrong. You are safe. Your friends are safe.
Inside this greenhouse, you feel secure.
