Why Do Memories Feel Like They Are in the Past?

Have you ever been startled by a loud noise and realized it happened just before? That is because your brain takes a moment to process the sound. When you remember that event, your brain places it slightly behind where your consciousness currently sits.

The Delay

Your eyes and ears send signals to your brain very fast, but not instantly. It takes about a fraction of a second for your brain to say, 'Hey, I saw that!' During this short gap, the world keeps moving. To make sense of it all, your brain groups these delayed messages together into a single bundle.

The 'Now'

Imagine you are watching a movie. If the audio is slightly out of sync with the video, it feels weird. Your brain fixes that delay so the loud noise and the flash of light feel like they happened at the exact same time. This creates your 'present moment.'

Looking Back

Because processing takes time, anything that happens before this short bundle is locked in as 'past.' It feels distant because it has been waiting for your brain to catch up. So when you recall a memory, you are looking at a snapshot of what your brain stitched together just a split second ago.

Examples

  1. You blink your eyes, but you do not perceive darkness because your brain fills in the gap with a continuous image of the world around you.
  2. When you drop a glass and it shatters, you feel the sound and see the pieces fall at nearly the same time, even though light arrived faster than sound.
  3. You are watching a race, and when the runner crosses the line, your brain registers that exact moment as 'now,' while the few milliseconds before are already stored in memory.
