If anyone is reading this journal I hope its from outside this dimension I have been pulled into. The only thing I can remember is being pulled into this mirror, its like half my memory has been wiped out. This dimension appears to be the same as our world. But with two differences. One there is no technology, that's weird because THEY invented these items. Two the people of this dimension are like normal humans but they have no eyes and are always grinning at a non human level. I have also noticed that there are no animals in this dimension. I will hopefully find a place to sleep and I will write in the morning if I make it.
Day Two: I found some food in a modern looking house. I heard footsteps outside so I went left through the back door. On my way to nowhere I saw a humanoid eating another humanoid. Then it spotted me and grinned with bloody teeth. And came sprinting toward me at the speed of a wolf. It tackled me and attempted to bite off my shoulder but it suddenly got shot by a man in an orange jumpsuit. The man had eyes and looked frightened instead of having a grin. He claimed to be a Class-D and he was sent here to look around. We soon agreed to find a place to sleep.
Day Three: We were just attacked by a group of the humanoids but the Class-D shot at them as if he were in the military. There were so many of them that he ran out of ammo so we decided to find scrap to make bullets. We examined one of the bodies and I recognized that they had only meat in them, no bones, no organs no anything except meat. We examined more bodies and they had different animal meats in them. I hope we find a way out of here soon.
Day Four: So much had already happened. My friend was eaten by a humanoid before I shot it. Guys humanoids just spotted me so I am writing as I run. These appear to be overweight so they run as fast as an adult human. I spot a mirror, its the same I got pulled into. If I don't make it I will I will throw the Journal as far and as fast as I can to get someone to read it to warn them.
Note: The Day Four paragraph explains why we never saw anyone get out of the mirror and why the journal darted out of the mirror. It is assumed that the man didn't make it out.
