When you think a thought (or have a memory), a biochemical reaction begins in your brain causing the brain to release certain chemical signals. That’s how immaterial thoughts literally become matter—they become chemical messengers. These chemical signals make your body feel exactly the way you were just thinking. Once you notice you are feeling a particular way, then you generate more thoughts equal to how you’re feeling, and then you release more chemicals from your brain to make you feel the way you’ve been thinking.
