Hhmmmm, well yes, the events within the episode were of a dream like simulation, however it was still inhabited by the minds of the P.I.E investigators, thus the knowledge told told the predates the episode, including the toilet toucher origin, as well as the mystery person ghost discussed unlikely to just be part of the simulation as well.

Within the Delphox mod, you can see toilet touchers ultimate form referenced again, and while it was another illusion it was also in the real world, as Ghost described an event he had with the entity.

As for the mystery girl of ghost often titled by fans to be Katrina. There were two horror episodes more or less dedicated to that enigma despite a lack of solid awnsers.

Perhaps I'm just being silly remebering things Jordan forgets or dismisses. But if there's any canon that is flexible or open to interpretation, it's the gmod canon.
