I had a dream I was being tortured but then killed myself?

I had the most disturbing dream last night. I was held captive by some disturbed person and they were slowly torturing me by stabbing, peeling my skin and just hurting me in all ways. At the end of my dream they left the room for a moment and I found a pair of scissors beside me and I cut my wrist deep, twice vertically so that I would die quickly before they came back. However theycsne back into the room and I showed them, then felt myself die and then I woke up. What could this possibly mean?!! I woke up drenched in sweat and scared but oddly calm?
