Dream About Harrowing Nighttime Encounter

I had two different dreams. One was very strange and gruesome. I was with a group of girl friends, and we had gone to a party. Now it was time to go home, and for some reason we were all walking back home at night. We were just talking with each other and walking by a sketchy area when out of nowhere we heard gun shots, screaming and then rifle shots nearby. All of us stopped at once, and we started looking around the houses and buildings to see where we could go. I found this abandoned shed and told everyone to come with me. We somehow snuck inside this shed, it looked old and it was dark inside but it had windows all over so the light from the streetlights was seeping through. Some girls were whimpering and shaking, and I kept telling everyone to stay quiet. But it didn't even matter... All I heard was footsteps and the nonstop shooting began. All the windows shattered and girls got hit. They killed every single one of them, and I was hiding underneath their bodies pretending to be dead. I wanted to cry but the shock and the fear of being found out was greater, so I just stayed still for what felt like forever. I could hear the men outside talking to each other, saying "was that all of them?". I woke up. Then I went back to sleep and that's when the second dream started. For some reason I was on my laptop in a public place, and I was conducting a hack on someone's credit card. I successfully was able to use their information to buy myself things, and some days went by where I kept abusing my power, and honestly I was being dumb about it and careless. Then one day I was on my computer when I get a notification from my own bank, with different charges happening all at once from different places, and somehow I just knew it was the person I had hacked! They had backtracked me because I didn't cover my steps, and were getting back at me. I thought of calling the cops but I didn't know what I would say... I was getting stressed out about not knowing how to fix this when I woke up again, and that was the end of it.
