Who attacked Gowther when he was brainwashing Dreyfus?


season 1 episode 18. I never did understand who attacked or was in Gowther
nightmare teller where he was brainwashing Dreyfus and why did "they" attacked
or showed up on Gowther brainwashing skill




Correct me if I'm wrong but I think it was Fraudrin because he was inside of
Dreyfus' mind/body and so he attacked Gowther while he was using nightmare
teller. At least that's my theory.
