- Hermione Granger: "You know, that really is extraordinary magic!"
- Fred Weasley: "For that, Hermione, you can have one for free."
- — Hermione's thoughts on the Daydream Charms[src]
The Patented Daydream Charm was a magical item created by Fred and George Weasley, sold at their shop Weasleys' Wizard Wheezes in Diagon Alley. Virtually undetectable, they were able to produce a very realistic daydream lasting for thirty minutes. Side effects of the product included drooling and/or dazed expression. They were not sold to customers under the age of sixteen, and like all Weasleys' Wizard Wheezes products, they were strictly banned from Hogwarts School of Witchcraft and Wizardry by Caretaker Argus Filch.
Hermione Granger found the product an extraordinary piece of magic, which was saying something, considering that she once stated the only thing the twins knew was "flashy stuff that's no use to anyone." For the compliment, Fred offered her one for free.
The colourful cover of the box Hermione was looking at showed a "handsome youth" and a "swooning girl" on a pirate ship.
