"You will find on the tables before you copies of The Dream Oracle, by Inigo Imago. Dream interpretation is a most important means of divining the future and one that may very probably be tested in your OWL."
Professor Trelawney[src]

The Dream Oracle was a leather-bound book written by Inigo Imago on the subject of dream interpretation.[1]

The introduction took twenty minutes to read,[2] and was known to provide some information on dream interpretation.[1]

It was required for Professor Trelawney's fifth year divination classes.[1] Professor Trelawney had already set them out on the tables in the Divination Classroom rather than having her students buy them and at the end of each lesson the books remain in the classroom until next time,[1] something unusual at Hogwarts.[3]

When Trelawney was placed on probation by the High Inquisitor, her frustration made her slam a copy of The Dream Oracle in between Harry Potter and Ronald Weasley, throw one at Seamus Finnigan so that it narrowly missed his ear, and thrust one at Neville Longbottom with such force that he slipped off his pouffe. When everyone was staring at her with surprise, she sarcastically asked them if she was such a substandard teacher that she never taught them how to open the book.[4]

  2. As a double lesson was an hour, a single hour must therefore be half an hour. Ten minutes left for dream interpretation subtracted from half an hour total class time equaled twenty minutes of reading time.
  3. The only other times students didn't need to buy their textbooks were when they already owned them (as with The Dark Forces: A Guide to Self-Protection in Moody's class) or (in the film adaptation only) Dark Arts Defence: Basics for Beginners given out by Professor Umbridge.
