Even in the dream world they need a nursery. Only this one is for a certain kind of dreamers, The fungi. It takes a thousand years for them to become adults, and about a hundred teachers who have already devoured thousands of books about 'how to raise fungi'. The fungi are very important creatures, they have to eat the old dreams otherwise these dreams can become nightmares. Nobody in the dream world is waiting for those terrible dreams. The last time the nightmares were there they disturbed the balance for years and years.
