Brain filters are what filter what you see and how you see it. They help you understand and recognize everything you see. If your brain filters are "clogged", you will begin to misunderstand things and mistake them for something else. If this happens to you, you need to change your brain filters. You can prevent damage to your brain filters by getting plenty of sleep.
I saw the letter w as zero today. My brain filters must need changing.
