Feelings are what allow us to record our sensory experiences through our neural circuitry and brain chemistry. When we remember an experience, we feel the exact same way we did at the time of the event. When we either consciously or unconsciously activate the associated neural networks of any experience (memory), the circuits we fire create the same, corresponding chemicals in the brain. These chemicals then signal the body. As a result, when we recreate a memory, we reproduce the same feeling in the body connected to the initial event.
