Has anyone successfully learned something from a shifted world and brought it back? Like you become a lawyer, study it in the DR, them back in your CR you're suddenly an expert lawyer? 


Or you improve your social skills by vast amounts? If not thats my big evidence for this shit just being a crazy realistic dream, if you can't get knowledge to bring back(I don't mean Harry Potter spell nonsense), because it means your brain is as limited as your knowledge
