🔹 Your brain constantly “draws” reality.
Your brain doesn’t simply receive an image from your eyes — it constantly predicts, fills in gaps, and constructs what you experience as reality.
🔹 Your brain itself can’t feel pain.
Brain tissue itself has no pain receptors. The pain you feel comes from the membranes, blood vessels, muscles, and other tissues surrounding the brain.
🔹 Your brain actively weakens or removes some memories while you sleep.
During sleep, the brain strengthens important memories while weakening some unnecessary information. Forgetting is a healthy feature of memory, not just a flaw.
🔹 The placebo effect can cause real physical changes.
Expecting a treatment to work can genuinely change pain perception and affect certain physiological processes in the body.
🔹 Your life “flashing before your eyes” may be the brain reacting to extreme threat.
When your life is in danger, the brain’s memory, stress, and survival systems can start working differently. Some people experience an extremely vivid “life review.” One hypothesis is that this may be connected to ancient survival mechanisms, but it has not been proven that the brain literally scans your entire life looking for a way to survive.
