To quote Juliette Mirovar.

“The mind palace relies on two interlocking factors. The fundamental mind palace discipline, and the use of the implant-laptop-Internet cloud to access massive data. The first is personal training and discipline, and the second is technology. The human-machine interface has a quirk. There is no way you can physically access the raw data and comprehend it. The technology creates a gestalt experience, essentially a vivid, lucid dream, where the information is presented in metaphorical imagery. A talented, and skilled loremaster can guide and interpret the dream to establish an augmented view of reality that approaches precognition.” - Juliette Mirovar, loremaster
