You might remember it in detail, but it's not as relevant to your survival as the data that your sensory inputs are currently taking in.

In other words, your brain doesn't give it the bandwidth (or focus) you want it to, because hearing what's around you, feeling with your fingers, thinking logically, tasting, seeing, digesting, etc. are all much more important to your survival.

And because they're more important to your survival, your brain will expend more resources on those things.
