Dream About Castle Yoga Teacher Hindu Symbols

I had a dream that someone was telling me about the story of this castle that was either owned or overlooked by my yoga teacher. My yoga teacher brought me to his library and told me about the history of this castle, different kingdoms, and their soldiers fought for territory and power and that their kingdom would strategically fight in these words as well. All these stories took place hundreds of years ago during the medieval times. then my yoga instructor said I should read these yogic texts and started putting books into my arms that were a light pink color And on the covers each had a different Hindu symbol.
