Never. 

Even though I have dreamt about some crazy and heartbreaking situations like witnessing my syster and mother die from  a car accident I caused yet, I haven't cried in that nor, any other shocking or sad dream.  Which is streange, and I must admit I have never thought about it before. Hmmm..... Is something wrong with me? I don't know.

I'm quite emotional and emphatetic irl so, I'm unsure of why I can't cry in my dreams.
