It was required for Professor Trelawney's fifth year divination classes. Professor Trelawney had already set them out on the tables in the Divination Classroom rather than having her students buy them, something unusual at Hogwarts.
When Trelawney was placed on probation by the High Inquisitor, her frustration made her slamming a copy of The Dream Oracle in between Harry Potter and Ronald Weasley, threw one at Seamus Finnigan 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 is such a substandard teacher that she never taught them how to open the book.

- ↑ 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.
- ↑ As a double lesson is 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 equals twenty minutes of reading time.
