ask me how I know. What they don't tell you though is that hallucinating isn't near as fun as it sounds, even if it's your waifu. Also, complete crapshoot if you even consistently hallucinate what you "want" to anyways.
Now, will that guide cause you to hallucinate? Probably not, but I wouldn't be surprised if with the right conditioning and mental state someone could do something similar.
