What is Real?

What is real?

How do you define 'real'?

If you're talking about what you can feel, what you can smell, what you can taste and see, then 'real' is simply electrical signals interpreted by your brain.

The system is a Matrix.  When you're inside, you look around, what do you see? Businessmen, teachers, lawyers, carpenters.  The very minds of the people we are trying to save.  But until we do, these people are not ready to be unplugged. And many of them are so inured, so hopelessly dependent on the system, that they will fight to protect it.

This is your last chance.  After this, there is no turning back.  You take the blue pill - the story ends, you wake up 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.
