Aliens and zombies, oh my!

Yeah, I know. It's a been a while, but I did say I was taking a small hiatus. The past 4 weeks have been a bit rough. More crazy shit going down, but that's pretty normal for me. So...aliens! And zombies! Aliens are out there! As are zombies. I, solemnly swear it. Tonight, the gang and I saw a meteor shower, but it was way more than that. We were all chilling and then..boom! Okay, so it didn't go boom, but it did crash....whatever it was. This dude got his head cut off and then he managed to put it back on and attacked us. So you know how in all the zombie movies, you shoot them in the head and they die. So didn't happen. We shot this zombie a gabillion times, blew its head off, blew holes in its chest and knees and it still kept coming, till I killed it. Yes, me. I took that zombie mofo down! But here's the creepy part. After I killed it, a tentacle came out of it. So far, I haven't stumbled across anything like this before. Any ideas out there?
