Companionship with the Dead
Interpreters have mentioned that seeing companionship with a dead person in a dream might indicate a long journey that brings much good. They also indicated that carrying a dead person on one's neck could mean acquiring abundant wealth and great benefit. Whereas, eating with the dead might suggest a long life.
