One thought process when you dream about orange juice is that you feel you need a fresh perspective on something if your current viewpoint is getting you nowhere. Or it's possible that you feel those around you are squeezing you of energy and time and you believe yourself to be drained at present.
If you dreamt of rotten juice, this can be a sign that your life is going to take a turn for the worst and you need to prepare yourself for some troubles ahead.
If you spill juice in a dreamscape, it's possible that your fruitful life is about to hit a rough patch and you need to put in some effort to clean up the mess and carry on or start over completely. Crying over it won't help- it's important to keep moving forward rather than dwelling in the past.
Freshly squeezed juice might be a predictor that good things are about to come into your life and the bad things are about to leave- a cleansing of one for the other- if you will.
If you were making juice in your dream this is a positive indicator of health if you are taking care of yourself in your waking life and are full of energy and vitality at present.
Another consideration is that you are in need of refreshment and nourishment- so perhaps you need to look after yourself better by taking on something new or by looking after your health. If you drank the juice, this is a positive sign that you will get the help you need to improve your circumstances or your wellbeing.
You know that work is inevitable if you want something enough and that to feel good you have to keep the momentum going. Eating oranges could be your subconscious telling you to re-energise yourself. Perhaps your health has taken a turn for the worst lately and you need to put good things back into your body in order to heal. More simply, your body might be craving Vitamin C as this could be the vital nutrient you need to make you well again. Oranges stimulate the senses when you peel and eat them so perhaps you feel the need to experience new things if you have become desensitised to the people, your routines and your surroundings in your normal life...
