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.
