There is a dream dish of zucchini - a sign that you have a pleasant lunch or dinner in the company of friends.
Zucchini — profit.
To play squash in your dream, suggests that you are trying to overcome certain obstacles in your waking life. You are displaying your aggressive nature. Alternatively, the dream may be a metaphor for wanting to "squash" something or somebody. You want to bring them down or put them in their place.
