Does this dream have anything in store for me?

I would take it as that you know that behavior is wrong and your brain is giving you a heads-up so if you actually acted like that you know that nothing good would come from it.

I thought you were older than this, maybe it’s because of your user name. Anyway it’s probably just saying that you’re sick of the general bitchiness and chatter of school life, and maybe it’s wish fulfilment, I think Freud believed dreams are just wish fulfilment, I’m sure he said more than that so feel free to correct me. It’s interesting how you couldn’t hurt your friend though, isn’t it?

Maybe people just piss you off and this dream is just a way of kind of letting your anger out without actually hurting anyone. And maybe you couldn’t hurt your friend because you don’t actually want to hurt your friend. What I find interesting about your dream is that you don’t get in trouble in your dream. I think if your mind was trying to give you a heads up like @johnpowell said, you probably would have gotten in trouble for your actions.

When I have dreams with strong emotions, I look at the emotions themselves to interpret the dream, not the actions in the dream. If I had that dream, I would interpret it as I am experiencing intense bottled up anger and frustration and want to lash out. Since, in reality, I can’t lash out without serious consequences, my psyche is dealing with it in my dreams to help me clear up the emotions OR is bringing my unconscious frustrations to the surface so I can figure them out in reality.
I find it to be a positive thing that this dream bothers you! I would be more worried if you found the dream to be inspiring.

No.

You got some issues to work out with some of your friends.

I think it was just a dream activated by what’s going on in your waking life at this time.. Incidentals, recognized faces, friends and even events within the dream could indicate what option(s) you would have to resolve whatever it is that concerns you in the waking state but little more.. The pounding wouldn’t necessarily indicate that you would like to do this to someone you know but as aggression itself.. Having the same opportunity (and desire) to do this to a friend but not being able to somewhat indicates that you have an issue with a thing and not a person.. This ‘thing’ could be very serious in your life or almost unnoticeable in the real world but because it affects (at times) it will appear in the dream state.. Your job is to decipher this dream because in almost all cases, what you dream is only an analogy of what it might be (if anything) because, you must also realize that it could only be an uncooked bit of meat..
