What is the summary of Harry Potter and the Sorcerer's Stone chapter 7?

Answer 1

The first years arrive in the Great Hall, where they line up in front of a very old hat, which they learn is called the Sorting Hat. After putting it on, it tells them which house they should be in.

Many different students are sorted into different houses, and finally it is the trio's turn.

Ron and Hermione go to Gryffindor; however the Sorting Hat wants to put Harry in Slytherin. He begs it inwardly not to, and is instead sorted into Gryffindor.

As the students are conferring about each other's lives and families, Harry looks up at the High Table and notices a man he later learns is named Prof. Severus Tobias Snape. When Snape glances at Harry, a terrible pain shoots through his scar, startling Harry.

Before Harry can fully react, however, Dumbledore ends the start-of-term feast by telling the students that a certain corridor on the third floor is off-limits. After this he sends them off to their dormitories.

Percy Weasley leads the Gryffindors to their dorms, and gets them in by way of a secret password ("Caput Draconis").

As Harry falls asleep that night, he has a nightmare, but when he wakes up the next morning, he doesn't remember having the dream at all.
