Fifth Dream + Strange Happenings

I apologize for not having updated in a month, but things have gotten a little weird over here by me. I'll start off by telling you about the most recent dream I've had (the other dreams I've had lately are just the same ones I have already posted about).

In this dream, I see myself from an outside perspective. I'm in what appears to be a warehouse of some sort, and I'm hiding behind a crate. Next to me is a man, dressed in what looks like a police officer's uniform. The difference is that one sleeve is completely ripped off, and the spot on the front of the shirt where the badge would normally be is completely gone. It's just a hole in the shirt now. He has a lot of stubble on his face, and he looks worn and tired, as if he had been through a rough time. He is talking to me, saying this is the last chance we have of taking him down, and if we fail here, it's all over. I ask him who he is talking about, but he ignores me. He suddenly pulls a flamethrower out from practically out of nowhere, announces it's time, and starts charging from behind the crate at a door nearby. I get up, pull out what appears to be a sword, and start running with him. Just as we are about to open the door, the cop disappears. I open the door, and I see the cop lying on the floor, lifeless. I wake up at this point.

I have been having this dream for about 2 weeks now with no idea what it could mean. However, I'm a little more concerned about what's going on in the waking world.

Firstly, I have been watching the news a lot and I'm hearing a lot of cases of missing children from my local area. No leads, no suspects, nothing. I'm not a father, but I always put myself in the shoes of the parents whose children are missing and get scared to think about what I would do. Second, I had to change the locks on my doors and actually put bars on my windows. For about 3 weeks, when I've woken up from my sleep, I think I see a man standing in the corner. A very tall man. I can't see a face because of how dark it is, but his presence there sends chills up my spine. I rub my eyes to try and get a clearer look at this person, but he is suddenly gone. I don't know if somebody has actually broken into my house, or if I'm just imagining things when I wake, but I didn't want to take chances. Tonight is the first night with the bars and new locks. If I see the man again, I'll know it's most likely my imagination.

So, any idea what my newest dream could mean?
