A sentence referring to the movie "The Matrix" in which 99% of the population unknowingly lives in a simulation. In the simulation, certain people learned that that world isn't real and so, if they believe hard enough can bend it to their will. An example of this in the movie is a child saying "The spoon isn't real" whilst bending a spoon with her mind without touching it. This phrase is sometimes used when doing something hard and thinking that if you believe hard enough, you can make it.
Jason had to hit a bowling pin with a football 20 meters away. He kept saying to himself "The spoon isn't real, the spoon isn't real" hoping it would help him hit the bowling pin.
