Do tu feel/think that our brains and bodies sometimes don't work together, are not in sync with each other?

A few examples: tu see a cute/attractive person, tu go up to him/her, and when tu are about to say something your brain immediately/suddenly just shuts down

tu forgot to say and/or do something such as when trying to recall an answer for a test/exam as well as the tip-at-your-tongue moment

Your body tells tu one thing but your brain tells tu another thing like pressing a wrong button por mistake o a slip-of-the tongue moment

Also I understand that our brains from time to time basically play trinks on us with optical illusions as well as misjudging distances as good examples
