A man once visited an old, abandoned asylum. As soon as he entered one of the wards, he got full body chills. He could swear he heard faint screams and moans. Another instance was a woman who was at a cemetery at night. She suddenly had full body chills and saw a strange glow near one of the tombstones.
It depends. Some experiences that cause full body chills might be based on real events, while others could be purely fictional or exaggerated for effect.
A woman once had an experience in an old cemetery. She was there to pay respects to a relative. As she was walking among the tombstones, she suddenly felt an overwhelming sense of being watched. A coldness enveloped her whole body. She heard a faint crying sound that seemed to come from nowhere. It was a truly spine - chilling moment for her.
Yes, full body chills can be a real physiological response. For example, when we listen to very moving music, or experience a strong emotional moment like seeing a beautiful sunset or being in a really inspiring event, our body can react with full body chills. It's related to the release of certain hormones and the way our nervous system responds to stimuli.
I'm pretty sure 'Full Body Chills' isn't a true story. It's probably just a fictional concept designed to give you chills and thrills without being based on actual happenings.
