Where does your mind go when you pass out ?

Nowhere: Maria, Just like when you sleep, your mind is still operating, you just aren't aware of it on a conscious level. There is a part of your brain called the Reticular Activating System which is responsible for keeping you awake. If it is off, you are not conscious. That doesn't mean that your brain shuts off, but it does mean that you are not aware of it, or awake to use the information.
