You know when you see something particularly horrendous, or sometimes even unexplainable.. I've heard the term "When someone walks over your grave", but what exactly causes that shiver down your spine when you get bad vibes?

Sudden physiological changes in the body usually occurr as part of the body's "fight or flight" response. That is, your body mobilizes stored energy to immediately protect itself from danger. Shivering is one such "fight or flight" response.
What basically happens is that small muscles at the bottom of each hair strand start to contract, making the hair erect. These erected hairs create a layer of insulation by trapping air, thus keeping you warmer.
When an animal gets scared, the same may happen in order to make one appear "larger" to enemies. So again, its a survival technique. When you get scared, nature can make your hair stand on end to scare away that...scary movie...!
