My dream was about me exploring, breaking the rules somewhat. It started with me convincing everyone to follow me to this other planet, a place where an official explorer team had been sent before. They were reluctant, since I think it was implied that we were to stay put and wait (which really didn't appeal to me). Anyway, I got them to follow me, but as we arrived and the exploration progressed, my confidence waned.
The team was nowhere to be found, and the place was deserted (not much more fun than the place we were waiting in originally). I ran ahead because I was beginning to get desperate for something to show the group, and I found an old friend, part of the official team. He'd been part of the grade above me in school, and his hair was lighter. He was tearing through a pack of some kind of food, salad or pastry (whatever it was it was meant to be eaten with utensils). I saw him first but he saw me right after. Clearly I would have wanted to hide, there definitely seemed to be something wrong with him. His wild eyes locked on to me and he smiled wide, didn't say anything too intelligent but only moved toward me very slowly if at all. I had time to leave before he could touch me (presumably the hypothesis at this point was that the whole team hadn't reported back because they'd gotten sick or something). I found a very weak member of the crew, an older woman (played by Filomena from work) who was pretty thin and frail. She seemed motionless but was conscious, so I thought it was safe to pick her up and bring her back to the group. They were closer to the exit and would leave when I was ready so I figured if we brought her back we wouldn't be returning empty-handed and at we'd have done good.
As soon as I brought her to show the group, she stirred, still in my arms (I was carrying her like a baby). Soon after opening her eyes, she looked at me, but rather than welcome the smile I was trying to give her, she just reacted to the closeness between us and rabidly bit the space between my neck and left shoulder. Clearly the disease gave her super-strength, or a huge mouth with teeth, 'cause she really tore in there! My reaction was like, 'Ow!!! Dude I thought we were friends!'
I pulled on the hair on the back of her head with my right hand as hard as I could (I had been trying to be nice until then). I don't know what gave it away (the looks on my colleagues faces?) but I realized that I probably then had whatever they had (the disease), and I screamed, "Noooo!"
That's when I woke up, and thought in hindsight that it was similar to the zombie facebook application.
