Exactly, I thought it might just be flavour text for how the killing went down, ReZ got his Ostrich to help him out a bit? But apparently there has been a disclaimer from Jonnas which acknowledges that it really was a dream.
THOUGH, ReZ admitted he did track him, so there was in fact an Ostrich there at some point, so I'm not sure what to believe because he must have let the Ostrich into his room which wasn't a dream and that is how the killer managed to get in?
