To dream of a mummy in a tomb represents an aspect of yourself that is remembered for its accomplishments or superior achievements.
To dream of a mummy chasing you or touching represents fear or anxiety about never being remembered. Terrifying yourself that you’ll be remembered for never having done anything important. Feeling useless or impotent. Feeling that you are never going to accomplish anything, become recognized, or make your mark on the world. You may be experiencing a midlife crisis.
Example: C.G. Jung once dreamed of coming after him. In waking life he was going through a midlife crisis.
