While it took us multiple attempts, and some creative usage of my magic to get around the dream realm's translation properties, we managed to work together to get a few basic phrases and an old folk song from his world fully translated. Included with this letter is a secondary parchment with the translations, as well as the original English version of each phrase, copied as to the best of my ability and memory, with the assistance of a memory spell. I hope that this will help you in your attempts to crack the language barrier.
