Red pill and blue pill

In The Matrix, the main character Neo is offered the choice between a red pill and a blue pill by rebel leader Morpheus. Morpheus says "You take the blue pill... the story ends, you wake up in your bed and believe whatever you want to believe. You take the red pill... you stay in Wonderland, and I show you how deep the rabbit hole goes." The red pill represents an uncertain future. 

I just have couple of blue pills to help me sleep
