Did the ancient mesopotamians believe the dead could attack e=them

The ancient Mesopotamians believed in an afterlife that was a land below our world. It was this land, known alternately as Arallû, Ganzer or Irkallu, the latter of which meant "Great Below", that it was believed everyone went to after death, irrespective of social status or the actions performed during lreward Unlike Christian Hell, the Mesopotamians considered the underworld neither a punishment nor a reward. Nevertheless, the condition of the dead was hardly considered the same as the life previously enjoyed on earth: they were considered merely weak and powerless ghosts. So, no.
