3 “haunted” !
They went ghost hunting, zim didn’t believe in much of this stuff until he saw dibs true origin of existence n saw the different creatures n phenomenons they encountered in their adventures. He believed only humans could be much affected by these ghosts n demons, well one ghost hunt went wrong. Dib was in danger, zim got in the way and experienced a sort of possession that whispered him terrible things, terrible fears.
Dib cried desperate to see him cry and salivate whispering in irken glibberish he didnt understand, it didnt last long and they ran away long after but it was the first time he feared for the boys life and sanity. Was what the ghost whispered true ? or a lie ?
