The Erratic dreams of StaySharp

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.
