Killing people in my dreams

its fear of killing not the desire to so its normal ive had similar dreams

Maybe you feel guilty about something? Try going over what happened in the last few days before you started having these dreams.If nothing happened that would make you feel guilty,maybe it's a memory from when you were young.If that's not it,maybe your family make you feel like you're not good enough or maybe you hide a trivial secret from them that you feel guilty about hiding? That's all I've got on that one- hope it helps.You can't find the solution without the problem.

Here's the important parts of what you wrote:

...killing people...accidental circumstances...girl I know...my friends...my brother...terrible... nightmare...unintentional...torment

Seems like you have a fear of bad things happening to people you love and you have absolutely no control over it.

It's normal to have our phobias/fears play out in our dreams. Maybe if you confront this fear when you are awake, you will stop having bad dreams about it.

whoa!... if this is a regular and often occurance, there is definitely some underlying issues that should be addressed. I'm not saying your psycho or anything. It could be stress, fear, anxiety, etc. How often are we talking about?

Are any of your other dreams as vivid as these? What do you feel when the ppl in your dreams are hurt? Not what you feel after you wake up, but in the dream. Try to focus on that.

Fact of the matter is that your subconscious is manifesting these thoughts/feelings in such a way to seriously disturb you and get your attention. It's telling you to deal with whatever it is.

yeah i used to ave alot of em dreams jus recently i had one of me on this thing out in the ocean and breaking my lil brothers neck and flinging him in the water then walking 5 minutes away then realising what iv done and didnt notice or could control wat i was doing then ran back and jumped in trying to save him but couldnt find him
i woke up and seriously i aint cried in a really long time i mean really long and takes something really big worse than a death to make me cry and i never felt so close to crying i got up and ran to my lil brother and spent like ages just hanging with him

Lots of anger about life. Better in dreams than in real life.

Couriocity? IDK If you're getting creeped by this then its best to see a counsler or something. Tell them you're concern and they can help.

it is normal, try during the day not think about it and you wont dream about it , dreams are usualy a mixed information of what you have been thinking during the day.
and be sure your not stressed before sleep cuz you can start sleep walking and really start killing people.
