In real life, we eat to satisfy physical hunger. Eating in a dream can be a sign that you need to satisfy an emotional or spiritual hunger.
It can mean that you are feeling spiritually or emotionally neglected.
Perhaps you are going through a difficult time and feel that others do not understand what you are going through and are not providing you with any support.
A dream that you are eating in a restaurant can be a sign that you want to be relieved of responsibility and be cared for by someone else.
A dream that an animal is eating you can mean that you are worried that you are losing control over your basic, animal instincts and drives. You are concerned about appearing uncivilized to the people around you.
If you dream that you are being eaten by another person, you feel that someone else may be using your emotions to manipulate you.
