A very vivid nightmare of getting shot, could someone please interpret this for me?

Hello everyone, this is the first message I post here. I just hat the most vivid nightmare and I was wondering if someone could interpret this dream for me.
Im a college student from Venezuela and I dreamt that it was late at night and I was in my car leaving a friend home (a girl I used to like, with whom I see some classes). We got out of the car and I walked her over to her apartment, and for some reason I was lecturing her about "freedom of mind" and "to be willing to think for oneselve" and I said something about kids. She didnt agree to this or she misunderstood me and she was rejecting me. Later in the dream, the same thing happened in a similar way with a girl I barely know, but once went out with (not on a date).
In some moment of the dream I had to take my shoes off and leave them somewhere in the building where this girl lived, and so I did, and I was fearful that someone might steal my shoes, but when I got back to them, they were there.
When I got outside from the building where I was (an unknown building with large front stairs), heading towards my car, there were a bunch of kids, not homeless kids but regular kids (aged 6 to 15 I guess), surrounding it. And there was a taller girl that was kissing all of them on the lips.
Well, here comes the awful part of the dream: In the car there was a friend waiting for me, this time it was a guy or two, the guy in the front seat (someone unidentifiable that reminds me of Marlon Wayans) told me that he had used my car to take all those kids to buy something, and I got mad at him for doing so without my permission, and I slapped him in the face, and in that precise moment I heard a gunshot, and I had the weirdest feeling in my head (like a buzzing and a bright flash) and I think I was shaking, and I realized that I had been shot in the head. About 50 mts away there was someone standing with a gun pointed at me, so I began to drive away, ditching the bullets that kept coming. I drove through confussing places cramed with houses, very reminiscent of some places where I have been, but there was not a place I could identify propperly. I got to a medical center, where they told me they didnt have enough supplies to treat me and thay I had to go somewhere else (In Venezuela medical care is not very good and I guess that got in my dream). I was feeling less and less of my body, and I was scared, and breathing very heavily. But still I didnt think I was going to die. I was hoping I could get some attention and survive this.
It was morning, all of a sudden, and a very crowded morning, as I walked looking for another medical center, and there was no one to help me: My friends had left or were simply witnessing what was happening to me, I walked through crowds of people looking for some help, but they were indifferent to me, they walked past me. I walked over to a tv reproter and a cameraman, but they didnt pay me any attention. I tried stoping a cab, but none stopped. A friend wearing black gloves offered me help, but I thought he was going to end up killing me, and I refused his help.
Finally I walked over to a medical center that was nearby, and I was feeling very bad, my heart was racing, and my body felt very cold, they told me that they couldnt operate me, but they would stich me and then I would have to go on my own to find somewhere where I could be treated. I was really scared this time, but acted calm, as I lied down wating to be stiched by a female nurse. I didnt believe I was going to die because of this, and I began praying, trying to make peace with the possibility, and my breathing got heavy, and the air got very cold, and I felt blood in my mouth being spilled over to the bed... And then I woke up, and I was very shaky, but managed to calm down as I realized that it was just a dream.
COULD SOMEONE PLEASE INTERPRET THIS DREAM FOR ME?
It was so very real.
