Precognitions Or Just Frightening Dreams?

I've posted quite a few stories on here. I haven't posted much in a while because things have calmed down in my house or at least feel like they are set in slow motion.

Over a 3 week period, I've had a few very frightening dreams. I can not tell now if they are precognitions, or if I am picking up on something that has already happened or will happen in the future (precognition). I'll list the three dreams below.

The first dream was set in my house and things were different. In my dream my mother lived with my grandma, sister, and I. In the dream my grandpa, who didn't look or act like my real grandpa at all, was in the hospital and returned home in the beginning of my dream. I went to greet him as he walked in the door, but a great feeling of unease came over me, and I was afraid of this man. He didn't say anything, he just walked in and looked around like it was the first time he'd ever seen the place. I told my mom something wasn't right about grandpa and she agreed. He then walked into the hallway where my mother and I were standing and started arguing with her, saying that she never told him I was part Native America (which in real life I am not). They bickered back and forth and my mother told me to go in my room, but when I did I was eaves dropping.

I heard a gun shot and I looked for some kind of protection in my room, and there was only a fork in sight so I grabbed it and ran out to see what happened, and my "grandpa" shot my mother, and he was on the ground, like he'd been hit and the gun slid into the bathroom. I stabbed him with the fork and scrambled to get the gun. Here's another weird part, apparently in my dream I had a 3 year old daughter and she was in the bathroom by the gun. She picked it up before I could and said "mommy, mommy, look what I can do" and I screamed no and she pulled the trigger and shot at my stomach once. I could FEEL the shot, it hurt like hell, I can tell you that. I could feel the blood coming out of my mouth as I tried to speak. I grabbed my phone and tried dialing 911 but I couldn't. I slowly walked out to the kitchen, dying, and my grandmother looked at me and said, "Now how did you do that?" and the dream ended.

The next dream was even more confusing. I was in this strange apartment building, but there was no exit and all the rooms were connected. I was trying to find my way out when a man asked me if I needed help finding the exit and I said yes, help would be great. He told me he needed to do something before he helped me and to follow him to his room. I did, and I waited for him in his living room. As I waited I noticed 3 pictures on his wall. The first was a picture of three, happy teenage girls. The second was of them also, happy, jumping around. The next picture was very disturbing, it was the three

Girls, but they were all dead. I started freaking out thinking I needed to get out of that place, but then the man came out and said "I see you saw the pictures" and he hit me a few times and made me do things for him. After this, he took me to the bathroom where he had a few knives hanging from the wall, and he hit me some more and told me to not do anything stupid, and that he'd be right back. When he left the bathroom I started looking for something, a way to get out but then I realized I had my cell phone. I quickly dialed 911 and spoke to the woman, telling her I didn't know where I was and that they had to hurry because he was going to kill me. She said police are on the way and I quickly hung up. The man walked back in the bathroom and said "I know you called the police" and right before me stabbed me, the police came in and got him. I woke up right then.

The third dream took place in a mall. I was with my good friend Caity shopping in this cool store, when all of the sudden these foreign men walked in and made a rude comment, so I gave them a nasty stare and said something back. They laughed and proceeded into the main part of the mall. We walked out and followed, and as we did we noticed more strange foreign men walk in the mall and started blocking and locking the exits. They took out guns and everyone panicked. I grabbed my friend and started running but I knew it was too late and they started shooting at everyone, and I got shot in the stomach, but twice this time. I felt these shots also, and it hurt like hell just like the shot in the first dream. Only in this dream, I fell to the floor and everything went black and I saw "the light" and I swear I could hear "angels" singing, at least I think they were angels. It was like all other sound was blocked out. This dream really terrified me, and I know I won't be going to the mall for quite some time haha.

If anyone can give me any insight on these dreams, that'd be great.

Also, now you can see where I'm coming from when I say I really have no way to tell if these are precognitions or real events from the past. I also have no TV at the moment so I can't watch the news, I can only look on the websites.
