Hi. I know there were other people in your dream but I wonder if there's any partial significance in this interpretation. It's from a dream meanings website I like to visit. It says [amongst other things]: "To dream that you are eating alone signifies loss, loneliness, and depression. You may feel rejected, excluded, and cut off from social/family ties. Eating may be a replacement for companionship and provide a form of comfort. Alternatively, eating alone reflects independent needs. Also consider the phrase, "what's eating you up?" in reference to anxiety that you may be feeling."

But, there were other people present in your dream as well, so: "To dream that you are eating with others signifies harmony, intimacy, merriness, prosperous undertakings, personal gain, and/or joyous spirits."

So, there's a few things there. Interesting.
