Angels are typically presented as benevolent celestial beings who act as messengers between heaven and earth. Most angels are represented by the image of a human figure with a halo and wings. Nymphs are thought to be imortal, divine spirits who love to dance and sing in the forests and meadows. Fairies are mythical creatures, human in appearance, with magical powers. Fairies love to play mischief on people and can play such pranks as tangling a sleeping child's hair into elf-locks.
