The interpretation of this dream depends on its details.
If you were happy in the dream, or if you were shopping and lots of business and selling was going on, it is a good omen of abundance and prosperity. But if the food (or merchandise) was in poor condition or smelled bad, or if the area was either empty or felt threatening, the portent is of difficult times ahead due to overlooked opportunities.
If you felt very overcrowded in the market, your dream is also telling you that you need to make some space for yourself. Create some solitude in your life, to reflect on a situation at hand and recharge your energy. Consider also the saying of “going along with the crowd” which implies conformity and lack of individuality.
