Your body also feels.
Every cell of your body feels something as you move, eat, or do whatever.
And your brain is just putting all the feelings together to organize and control them.
Your body makes you see dreams at night when your brain is sleeping.
Don't you remember having some bad dreams when your stomach was upset? They are trying to tell you something by using memories that are stored in your DNA. Sometimes, from memories of previous lives.
That's why you can see things that you have never seen in this life in dreams.
