All I remember was that this was a video game dream. About solving a mystery. It was probably a Sherlock Holmes -esque Victorian thing in London, though you couldn't actually play as Sherlock Holmes, you had your own character. At one point you could find random pistols on one passageway floor and examine the bullets, kind of in Bioshock/Dishonored manner. All of the characters moved independently and sometimes they had to go to face other characters elsewhere.
At one point you went to some industrial area/loading dock where people were waiting for some robed monk/secret society characters to escort them to the sewers.
At one point, I decided to go undercover and I went to one two-storey wooden building where a lot of witches were sleeping. They weren't good or bad people. They were dressed kind of like Morrigan from DA: O, but not quite. All of them carried this weird crooked staff that had weighty thing with moons and discs in the end. It was kind of awesome.
That's where I woke up or something.
