I often get what can only be described as lucid nightmares. I can feel every sensation in my body (down to sexual impulses) but when the nightmare kicks in I won't manage to wake up without screaming. The thing is, I live alone so in my dream the screaming is muffled and almost useless. I have no idea if its actually loud in 'the real world'. I am almost certain its connected to past trauma given the subject matter in the dreams. It's crazy what the mind can do when you try and get a good night's sleep.
