What is the difference between Ghosts and ghouls? Is one of these scarier than the other? Maybe.. It is said that Ghouls are evil and feed on the dead. But Ghosts, were once human. And we all know that the human experience is much more complex than ‘good or bad’. Today, in between the ghouls and ghosts of your past, you may find yourself considering the grey area. If in doubt, decisions are best made with conscious contemplation.
