Do End Of The World Dreams Mean Anything?

On the night of February 22, 2009 I had yet another "end of the world" dream, that's just my term for them. Anyhow recently over the past year and half or so I've had three Armageddon/revelation/end of the world dreams. I usually wake up abruptly and realize that I have only slept for one hour. Almost all of these dreams involve comets hitting the earth. This fourth dream was a lot more realistic than my other ones because the setting took place within and around my house. The images are still very fresh in my mind.

It starts out with me standing in the driveway in front of my house, my mom and sister in the garage, when I notice that a storm is heading towards us, I also notice that there's this really big and fluffy cloud off to the right close by and it stood out because it was white contrasting sharply with the darkening sky. As I'm looking at the cloud I see a white lion along with another thinner figure standing next to it, they were both sort of translucent yet luminescent at the same time, kind of glimmering. I presumed that it was Jesus because of the whole "lion and the lamb" thing and because his face was bright and I couldn't quite make out the features but I just knew it was supposed to be him. He then raised one arm up and pointed directly at me and I'm not sure if he said anything or if I just heard it in my head but he said, "I love you, little one" and I thought wow that was really weird, especially because he pointed directly at me.

Then I glanced over and I could see behind my house in the somewhat close distance a large black/gray cloud sorta looked like it could be really thick smoke too--and it rose very high into the sky and there were flashes of lightning. I told my mom and sister to get inside because of the huge storm. And when I got inside the lights flickered as if the power were going to go out at any moment, so I started trying to get some flashlights. Then I happened to look out the window and saw that the skies were darkening as the cloud grew larger and closer. I looked over to the left and there was a man in the dark cloud--he really looked like a man that was just larger and in the clouds. He had a knife thing in his hand and his face was in a shadow so I couldn't see who it was or make out any features.

Anyways I watched him strike the cloud in a downward stabbing motion with the knife and each time he did, a reddish-orange streak would shoot up into the sky and disappear... Sorta like when you watch fireworks. This happened several times and then I watched as one of the streaks went into the air but it didn't disappear instead it seem to arc in the sky and shoot in my direction and I could see that it was a flaming comet and I ran downstairs and yelling about getting under cover and that the things I had been dreaming about were coming true. I watched horrified as comets hit the yards of my neighbors' house, some streaking narrowly past ours and I was scared that one was going to crash into our house, right before I woke up I realized that none of the comets were hitting our house, they all seemed to be avoiding our house.

One of the significant things that I noticed about my dream was the presence of only my mom, my sister, and me. My older brother and my dad were missing from the equation. My brother and my dad are both not Christians and I found the fact that they weren't in my dream may mean something but I'm unsure. Anyways these dreams always scare me slightly upon awakening and I wonder if the frequency and recurring theme of these dreams is some sort of message or just an unusual coincidence.
