Answer:
Indian Burial Grounds are believed to be places where native Americans buried their dead. However, what makes them interesting is that they get a lot of blame for supernatural happenings, such as ghost hauntings.
Some very superstitious people believe that some burial grounds had the power to bring people back to life f they were buried there.
A good example of the is Stephen King's "Pet Sematary" (and yes, it is intentionally misspelled).
I hope this has helped a little :)
