Is Reality Even Real? Your Brain Constructs the World You Experience
7/2/202650 min
What if you've never actually experienced objective reality?
In this episode of Decoded, Elisabeth McKay explores one of the most profound questions in neuroscience, philosophy, and psychology: How does the brain transform information into the world you believe you're experiencing?
From color and sound to pain, emotion, memory, and meaning, your brain isn't passively recording reality—it's actively constructing it.
This episode breaks down how perception is created through predictive processing, sensory translation, and childhood conditioning, revealing why two people can witness the exact same event and walk away with completely different experiences.
In this episode, Elisabeth explores:
- Why your brain never directly experiences reality
- How the brain constructs color, sound, touch, and pain
- The neuroscience of perception and consciousness
- Why atoms are mostly empty space
- Predictive processing and Bayesian brain theory
- Interoception and its role in anxiety and panic
- Phantom limb syndrome and the brain's model of reality
- How childhood experiences shape adult perception
- Why memories and emotions influence every experience
- Brain Pattern Mapping and the roots of self-deception
- Why objective reality and subjective experience are often confused
Reality may exist. But your experience of reality is constructed. Understanding that distinction changes everything—from relationships and communication to anxiety, trauma, emotional regulation, and mental health.
This is Part One of a two-part exploration into perception, consciousness, and the neurological foundations of reality itself.

The brain is constantly forming assumptions, and these are hardwired rules about what is going to happen, what it expects, how it should engage. And often these rules are not in alignment with how present reality is showing up. If this can happen with things like color, sound, physical touch, pain, what then are we to do with our interpretation of emotion and what somebody means, intention, motive? Do you see how gray this gets? Your brain is wired for deception, but here's the truth. Patterns can be broken. The code can be rewritten. Once you hear the truth, you can't go back. So the only question is, are you ready to listen? What if I told you that you've never actually directly experienced reality? It sounds absurd if you actually think about it. And if you're listening to this episode right now, maybe you are driving down the road. Maybe you're working out. Maybe you're folding laundry, which I certainly could be doing myself right now. Walking your dog. Maybe you are sitting, sipping a cup of coffee, which I have right here with some nicely frothed almond milk. Mm, delicious. This room around you and everything that you're interacting with feels real. The sounds feel real. The smells feel real. Your body feels real. Everything
