Gladiator
To dream that you are a gladiator represents a situation where you are fighting for your survival. You feel that others are working against you. Alternatively, the dream means that you are confronting issues from your subconscious.
Machinery
To see machinery in your dream suggests that you are too mechanical – going about your way without much thought and making decisions without thinking it through. You need to get out of your boring pattern. Alternatively, the machinery symbolises your mind or your body. Examine how the machinery is running and its condition and function. If the machinery is in need of repair, then it suggests that you may need to repair aspects of your self-image or a relationship. If the machine is rusty, then it signifies an outdated way of doing something.
Heart
To see your heart in your dream signifies truth, courage, love, and romance. It is representative of how you are currently dealing with your feelings and expressing your emotions. Also consider the saying “the heart of the matter” which implies that you may need to get down to the core of a situation before proceeding.
