Coast to Coast Ghosts

In the book Coast to coast ghost , by Leslie Rule , i read read chapter three , school spirits . This chapter talks about soem famous school hauntings across the US. in the first story River of death , they claim a school in the town of chickamauga  is haunted . They blame the cause on spirits form a civil war 2 miles away many years ago. I don't think that solider spirtits would really haunt a school . wouldn't they haunt the battle field? Otherwise i believe the spirtit stories in the readings . How lights will turn on when noones there with no explinations and hearing footsteps . Each small story and sample of hauntigns in schools across the untied states gives evidence of true fact , that can scare people . I think people fine them scarey becasue there unexplained . If they were explained people woudln't be as scared because they'd know why .
