“There is no reality, only perception. Identify the filters through which you view the world.”
-Dr. Phil
Imagine this scenario. You’re sitting at your desk, on the phone. You want to write down a number so you reach for a pen and a piece of paper. But as you reach for your pen, it becomes smaller and smaller till you wonder if it’s even there or just a hallucination. With some struggle, you pick up the pen. You reach for a piece of paper but now that seems to messing with your mind too. The paper becomes bigger and bigger till it covers the whole room.
Are you going crazy? Relax. You’re not.
