If you find that you are crying in your dream it could be a reflection of how you are feeling in waking life?
If someone else that you know is crying in your dream it could be that you need to look out for them, that they need your help?
If the person in your dream that is crying is someone you don’t know, try and remember how you feel about them, what emotions were attached. It could be that whatever they represented in your dream has a connection with that part of your self, so that part of your self needs attention.
If you wake up crying it could be that sadness in your waking life is also finding its way into your dreams?
Crying is not always connected with sadness, you may be crying out of frustration or crying for help. It could be that you are repressing a lot of feelings and emotions in your waking life, so much so that you find it difficult to cry? If this is the case your dream may be giving you a way out, letting you cry to release some of those pent up emotions?
So, crying in your dreams can be your subconscious mind’s way of helping you overcome grief or sorrow, or showing you that crying is helpful.
Perhaps you are currently going through big changes in your life, and your dreaming mind is lamenting the past life you are leaving behind? Or perhaps your tears are false, or tears of joy?
