There have been reported cases over the years of human skulls that have screamed when attempts have been made to move them from their last resting place.
It is reporting to be a loud terrifying scream.
In each of these cases it was found that the owner had left specific instructions on what was to happen to their body after death.
However, it seems that these instuctions were ignored.
It seems the ghost is using the skull as a medium to carry out hauntings.
The only way to put the matter at peace is in some way to try and follow the instructions that were left behind as best as you can.
