There is a partially-lucid dream I had several months ago that I can still recall in excellent detail. It's one of the few times where I've dreamed in both first and third-person view (those who are sensitive to some graphic content are recommended to skip reading).
My family and I were sitting at a picnic table in a small grass patch close to a large mall, and I had one of my cats with me. I decided to get up and leave the picnic table after nothing interesting happened, and I was getting bored, so I decided to walk into the mall and see if I could catch a good movie or something. I had never noticed until later, but my cat was following closely behind and she followed me into the mall.
I wandered throughout a large hallway filled with many shoppers and a central bench with a lush, green fern, looking for the movie theater, but I saw something that interested me even more: a partly-open wall panel with a paper sign posted on it that had "DO NOT ENTER!" printed in red. My curiosity got the better of me, and I forgot the movie theater and entered the restricted area. I gingerly closed the panel behind me to make sure that nobody would suspect anything.
The new area I entered was completely empty, save for walls made of glass panel that stacked themselves to the high ceiling, where a skylight beamed sun rays down, making the glass panels glimmer and shine. I started to wander around and explore when I came upon a dark corner, where I saw the silhouette of a person. I slowly approached the corner to examine the person in greater detail until they emerged into the light. It was a police officer who spotted me, raised his hand and said,
"Stop! You're not allowed in here!"
"Why not?" I asked.
"There's a problem... We're not allowed to explain it now, but you'll know when the time is right."
"Oh, okay." I replied.
"Allow me to escort you out of here," continued the police officer. He courteously approached and started to motion toward the exit, until I noticed my cat, except she hardly looked like my cat. Her face began to deform itself, growing larger and spurting multiple red eyes. I counted eight of them. Her fur began to grow a sheen of green and her back became permanently arched, and she hissed and growled at the police officer and me. Around her body was a cloud of green which appeared to originate from the dark corner. The police man shouted in fear, pulled out his pistol sidearm, and killed what was once my cat.
"We need to get out of here!" he said with urgency. Suddenly, a man who was dressed in a white laboratory coat and looked very much like Dr. Isaac Kleiner from Half-Life ran out from the dark corner and yelled,
"Get out! Get out of here! It's too dangerous to stay here!" The three of us began to hustle back toward the movable panel, and we entered back into the main hallway. Chaos and panic was amok in the hall, as malformed, snow-white humans covered in enormous soccer ball-like pustules attacked normal humans, beating them and eating out their throats while small ball-like creatures scuttled across the floor, jumping on the dead humans, latching to their open, bleeding throats. The humans began to transform into the mutated forms that originally killed them, and started to attack other normal humans (proves that I played too much Halo :P).
"Too late! The infection has begun to spread!" shouted the scientist. "There's a safe room on the other side of the mall! Run for it!" We began to sprint through the crowd, punching mutated humans out of the way while the police officer opened up on ones attacking normal humans. The police man was overwhelmed from behind however, and he was mauled by the mutants. I watched in amazement as he was torn open and mercilessly slain, but continued to keep running for my life.
The door to the room that the scientist mentioned was in sight: an enormous, black, steel door at the end of the hallway loomed in its majesty. Unfortunately, the scientist ran into one of the mutants, and he was beaten to a bloody pulp and killed. I arrived at the door, pulled it open, and slammed it after I sprinted in, trapping the fingers of a mutant and cutting them off. I fell back against the door, sighing in relief. As soon as I was finished relaxing though, I saw several faces in shadow staring at me in bewilderment, but one of them approached, a young, brown-haired man, and he said,
"It's good that you've made it. It's safe here."
I relaxed, took another deep breath, and walked toward the faces in the dark where I could see them better. They were all around eighteen to twenty-three years of age, and they all had the same blank look on their face.
"We're all staying here," said the same man. "We can't get the police out here; they've been infected, like the rest of them." I sat down with the rest of them and studied their faces while they studied me; a silent session of acquaintanceship. A brown-haired girl leaned on the shoulder of the same brown-haired man as we listened to the horrifying screams, gurgles, and cries of the slaughter victims outside.
We sat and waited for several hours, and I fell asleep a few times (which was weird, considering how I was already asleep), but the carnage started to die down and the screaming began to minimize. Over time, a smell began to seep into the room: a mixture of blood and sulfur. All we could do was sit and wait.
At about nightfall (we could tell the time of day by looking out of a small window), the brown-haired man said,
"That's it. We're not staying cooped up in here waiting to die. We escape tonight."
"But... What if something happens to you?" said the girl who leaned on him. "To us?"
"We need to get out of here. We need to tell somebody. Then, the military will come, and this whole mess will get cleaned up."
"Okay..." the girl replied. The man then turned to me.
"We have armaments that we've taken from downed police and SWAT officers. The ammo's limited, but it's enough to defend ourselves."
"Okay. When do you want to do this?" I asked.
"A few minutes. Load up."
I took a tactical shotgun, loaded it up, and waited for the others to finish preparing. The brown-haired man went to the door and grabbed the handle.
"Ready?" We all nodded. He swung the door open and shouted "Go, go, go!!" My eyes were blinded, as I had been sitting in darkness for hours, and the enormous, cylindrical lights which hung from the ceiling were still turned on.
I saw the same mutants as I had seen before, but now I saw several enormous mutants which looked to be nothing but enormous pustules, stacking several feet high. We violently fought our way through, and I watched several of my comrades fall (I would go into greater detail, but I might get flagged for being too graphic), and after several minutes, only me, the brown-haired boy, and the brown-haired girl remained, and we sprinted out the main glass doors, and I ran like hell. I could remember hearing nothing but the running of our footsteps on the grass against the pure silence.
Then, suddenly, my view changed from first to third person, and my view went back into the mall where I quickly took the place of one of the super-mutants. I could feel everything of its anatomy: new appendages, shifted weight, and all that its nerves could detect, especially the throat. I took control of the super-mutant, and I let out an enormous roar, vigorously waggling my arms. Then I woke up...
Sorry that my post was REALLY long, but I remember this dream in full detail... It still slightly haunts me to think about it.
