Blue Flame's nightmare

Blue Flame awoke "What the..." he muttered weakly as he attempted to stand. He had a headache that made him flinch in pain. As he tried to remember what had happened, he examined his surroundings. He couldn't find anything out of the ordinary, but something felt...wrong. Almost as if there was a nearby presence, watching him just outside of his line of sight. It made him feel uncomfortable but there was nothing he could do about it at the moment. He tried his hardest to remember what had caused him to lose consciousness, but to no avail. He looked up at the clock, it was nearly ten o'clock. It was odd that nopony had stumbled upon him in the lab, but he would have to deal with that later. He had to get home to Carrot Top and his sister they must have been worried about him. He wouldn't be able to teleport with a headache like his, he would have to take the old fashioned way. When he exit the building there was a thick fog. It was too thick for him to see more than a few meters in front of him. As he headed towards the direction he was sure was home he noticed the strange presence he had felt was getting more intense. He wasn't even sure why, but he felt afraid, very afraid, now in a fast paced trot he stopped finally realizing that he hadn't been paying attention to where he was going. There was a tree nearby, he walked up to it. It hadn't been like any tree he had usually seen around Ponyville, something about it was...'twisted'. He looked up at the tree and was horrified to find there was a large branch impaling the rotting corpse of a pony, he wanted to vomit. He was now completely terrified, he couldn't even imagine what horrible monster would do such a thing. The tree branch fell down hard next to him and he yelled in surprise. He saw that the branch was still connected to the tree by some sort of cord, he tried to make sense of it all. Just then the corpse sprung to life and lunged at him, it knocked him to the ground cutting one of his hind legs and he panicked, kicking wildly he landed a kick on the cord that still connected the creature to the tree. It screamed in pain and flailed itself around, blood pouring from the newly severed cord. It died leaving Blue Flame with his eyes wide open, covered in it's blood, and more terrified than ever. His mind was racing with questions, what was that thing, why did it attack him, and most importantly how did it get there? His head started beating like a drum and he winced. He examined his surroundings for any landmarks he could find, there was a figure of a nearby building and he headed towards it in hopes that it was nearby to his home. He stopped dead in his tracks, it was the lab. He was very confused by this, but he wouldn't be able to think about it right now, not with his level of headache. He slowly walked to his workstation where he yet again passed out on the cold hard floor.
