Write a story about any of these.
Maybe someone finds a unicorn in the garden. Perhaps the statue of the dragon in Krakow comes to life one day. Maybe a cyclist is killed on the road through his own recklessness and comes back as a guardian angel to the remorseful driver that accidentally killed him? I don’t know which or any of these could work as a story, but it would be interesting to see what I can come up with. Have a go, have fun.
