Anyone else ever had a nightmare like this?

I was out with my parents at night, and these two guys with skull masks and guns came up. I was terrified but utterly determined to protect my parents even at the cost of my own life. I didn't actually believe that this thug would shoot so I charged at him... And I can so vividly remember the loud shots and explosive pain as he shot me multiple times in the chest. Finally I collapsed and I remember so clearly, lying there knowing that I was about to die and feeling... disappointed, because I had failed to protect my parents and because there was so much I hadn't gotten the chance to do. Gradually the incredible pain started fading away and I knew without a doubt that soon I wouldn't be able to feel anything at all. I was absolutely certain that death would bring nothing but oblivion -- I wouldn't be capable of 'regretting' or 'missing' anything, or even to think at all; once my brain shut down I would simply cease to exist. It seemed like such a waste. And just as my existence was about to blink out, I woke up.

It was so uncanny. I bounded up and started feeling for the bullet wounds only to find none. It really shook me up; I know it was just a dream but it felt so real.

To be clear I don't think it meant anything; it might just have been because I've been thinking about death a lot lately. I'm just wondering if anyone else has ever had a similar dream that seemed hyper-realistic.
