When you practice your reality checks, be sure you are really increasing your awareness. Really ask yourself if it is a dream, expecting it to be one. Pay special attention to your surroundings and your memories of the past few minutes. How did you get here? Why are you here? Does this feel like a dream?

The goal is, by the time you think to do the reality check, you already know it is a dream. The reality check just proves it and gives you a minute to focus on it.
