Queen Mab is a character from English folklore, often depicted as a fairy or a queen of the fairies. She is known for her role in influencing dreams and is associated with the idea of dreams as a source of inspiration or mischief. Her name is famously mentioned in William Shakespeare's play, "Romeo and Juliet," where she is described as a bringer of dreams. In literature, Queen Mab is often portrayed as a small, delicate figure who rides in a chariot made from a hazelnut.
