The Erratic dreams of StaySharp

The infected plains:
A really creepy dream about a big piece of land with all kinds of different grounds, at the start of the dream I was seeing a map of the place with different colors for different types of ground (including things like: stone, sand, grass, shallow water, deep water), they were also labelled with numbers from 1-99. I think the 99 meant no human can normally pass through, which I think was assigned to deep water as normally passing through was defined by walking on it.
I was walking around together with someone else, and there were somehow infected humans who had a horribly distorted voice and language, who obviously were dangerous, the higher level infected ones however were able to imitate normal behavior to be able to more easily infect others. A part of me was unaware in the dream immersed, yet I had another part watching and knowing about their infection and the danger. In the end the combination of both sides compelled me to touch an infected cat which then made strange noises and gave me a scratch on the leg which woke me up.

Spear gun trip:
I was laying out some type of magical traps in this slightly western like looking city (the street however was very sloping and really narrow) and some people started shooting at us (whoever was there with me didn't follow me though), I picked up a bit of ammunition and got my spear gun (Bioshock 2) with some rocket spears ready.
But as I went around the corner the dudes were gone and I found myself in a slightly dark underground complex, there was a sniper (TF2) whom I missed with my first shot, he decided to taunt me and got himself a rocket spear in the face, then 2 scouts came for me from the level below and I immediately hit one of them with a rocket spear, the other one using the stairs to come after me. After a undetailed fight I was searching through my weapons, confused not to find the weapons in the order I'm used to. On slot 2 I found some types of wine of which I used so called Sourwine to attack him and inflict acid damage.

Strange mission:
I was having a mission together with a companion (a girl slightly younger than me if I recall correctly), through some gestures I send her to get something (a small thing, maybe a key) while I myself was going in the opposite direction. From the green hills I was walking on a short moment ago I come into this dark place where a lot of magicians gather some strange points, they were my enemies and I tried to take them out one by one without getting the attention of the whole bunch.

I went into a big swimming bath complex (one of my few dream signs) and there was a virus around. It infected people and the only real first symptoms were minor behavior changes and trying to infect other people (simply by being close to them, the virus spread through air). When fully infected those people would generally behave normal except for building big groups and staying together, as well as preventing anyone to leave the group. As I went inside I understood the situation but all possible ways to escape the building were too far away, however I was immune to the virus so I disguised myself as infected. I remember being on a high tower (20m) within the main room with all the water and someone of the group wanted to check me (probably if I was infected already), but I noticed she sent someone towards me and headed to her myself and made her believe I was a normal part of the infected group, afterwards I was looking towards the big windowed side of the building trying to figure out a way to get out.

I had a dream about Andromeda (the series) where Dylan had a mission to escort someone on a planet. Seamus Zelazny Harper and someone else (another unknown engineer) were facing a special threat meanwhile, someone who had a lot of different people in his matrix. Actually Harper nearly died some years ago in an accident but this dude probably killed him himself while Harper was resting, uploaded him into his matrix and replicated a Harper to infiltrate the crew. Harper however managed to understand the Situation at some point and programmed a virus inside of his mind, and uploaded that virus into the dude during that mission. Thus he was able to take him over and sort of get himself resurrected. On the same Planet there was a spot of space (distorted physical laws) where Beka was fighting some sort of huge technical Pyramid with the Maru. Harper used his new (pretty advanced) space-proof body to save Beka out of space after the Maru got destroyed in a fight during the same mission.
