What is the setting of Next to Normal by Brian Yorkey?

The most interesting thing about the setting of this piece of theatre is that it moves in and out of reality - specifically, in and out of actual physical settings (i.e. the family's home, the doctor's office, the operating room), in and out of the characters' minds. The most vivid, and dramatically effective, of the latter is the relationship between Diana and Gabe, which takes place almost entirely within the boundaries of Diana's imagination; he's not alive, he is a delusion, a product of her imagination and fantasy ... a product of her mind. Here it's important to note that while Diana is the only character who interacts with Gabe directly, his presence is also a manifestation/externalization of the minds of the other characters - Dan's memory and assumptions, Natalie's memory and resentments.
