Dropped Ghosts

The entities in another dimension finally communicated to me the meaning of their rant, "qradoooozaaaaahhhn rapusahhhh kalaboriotesopaaaaah ruffffff kappppaazzzzzz." Ghosts are not leftovers from the dead. Rather ghosts accidentally got dropped onto Earth. The entities in another dimension want me to return the ghosts. How can I send the ghosts back to another dimension?
