I woke up in tears

I had been dreaming that I was sailing in shallow water, past a beach, in some Caribbean-type place. But the natives of this place were being tortured by having hundreds of sewing needles inserted under their skin. I don't know if I was a native or not, but I hadn't been tortured yet. I felt so helpless for those that were suffering that I started crying in the dream, and I woke up sobbing. It's unusual for me to have such strong emotions that would manifest themselves physically. It is also not normal for me to cry much at all.
