Dream of Piers (also known as Nightmare) is a non-combat pet in Diablo III, added in patch 2.4.2. Players can obtain it by participating in Season 7 or 19 and having beaten Chapter 4.
The Scribe known as Piers was haunted each night by this being.
- The name and description of this pet are a possible reference to the Night Mare by Piers Anthony.
