Ghost Rappings are one of the earliest means of spirit communication.
Rappings include thumping, knocking, tapping or bumping.
In ancient times Ghost rappings was thought of as an omen of approaching death.
It was during the time of the Fox sisters that rapping gained widespread public knowledge.
It was during this time that a number of fraudulent people set up business claiming to communicate with the other side.
The Fox sisters later admitted to tapping the floor with their toes.
This is not to say rapping is not authentic, but it just shows that these things must be authentically investigated.
