Dream of attack and killing attacker

I just woke up from this horrible nightmare and still have a lingering bad feeling even now. I dreamt that I was at a beach with my friends and decided to venture off behind a bend. I was in waist deep water when I felt someone attack me from behind. It was a very large/strong man that looked much like an ogre... I somehow knew that his intentions were to rape me even though he didn't speak to me at all. I grappled with him, trying to throw him off but I could feel his limbs around me and they were bogging me down. I was also struggling to move as we were in the water. I remember wondering why my friends were not coming to my aid since I was still within eyesight of them.... At that point when I felt that I was definitely going to lose, I reached out with my left hand and felt around until I felt something hard. It happened to be a spoon. The next thing I know I'm violently smashing his face into a bloody pulp and killing him.

What do you think about this dream? I am currently battling a chronic health condition, and I wonder that this may signify feeling that I'm battling this alone. What are your insights?

The dream is about battling a chronic heath condition. We all have to heal within one self. The we all do battles alone, even when we are seeing a professional. You are actively engaged in your own healing in this dream.

I too have these except they happen while I am awake when I walk past somebody. I get these flashes or videos in my mind and see him attack me and I react first.
