A sheet of paper in a dream means that pettiness can make your life more difficult.
see a sheet of paper: you will have a lot of troubles because of some matter, you will have to make some brainstorm to solve it
write something on a piece of paper: someone is waiting for a message from you
read something from a sheet of paper: look carefully around you, not to miss something important
flip through the pages, spilling: you are fickle in your beliefs and unfaithful in feelings
