If you see yourself eating something on your own, then such dream symbolizes the loneliness, unhappiness, grief and losses. Perhaps you are feeling neglected from your colleagues, friends or family. The eating could also be interpreted as something you are holding on to when you are feeling sad and bad in general. If you saw yourself eating with other people such as your family, friends or colleagues, then it shows the great achievements, growth of friendships and overall happiness. If you are eating very little in a dream, then such dream indicates the shortage of goodness you receive from life. If you are overeating, then such dream shows the greed, which should be taken away. If someone else has eaten your food, then it shows the unexpected obstacles from those you have trusted.
