This is not restricted by singular and plural. eg It all up to you.

2 I once believed in the American Dream, which meant a job, a mortgage, credit cards and success. I, like everyone else,

pursued this dream and fought for it. We all pursue the same dream in different ways.

One year, after experiencing a series of unfortunate events, this dream fell into pieces. I was homeless and alone. All I have is a truck and $56. I went to the countryside to find a house where I could afford the lowest rent. I happened to find a shabby house on the Virginia River, four miles from the winding mountain road.
