Just the other day, I was speaking with someone and they started talking about Hawaii. It then snapped in my mind about a dream I had just had that night about meeting an old woman who lived in Hawaii. During that conversation with the woman, she alluded to an ‘exclusive’ area of Hawaii named River Crest or something. Now, having never been to Hawaii, I wondered, where did my mind come up with this ritzy area? Which then made me think about all the dreams I’ve had in Japanese where I’ll be speaking with someone, they say a word that I don’t understand, and I ‘learn’ a new word–only I can’t remember what I learned when I wake up. In the case that I did remember that new Japanese word, or the name of that ritzy area, would those places/words actually exist?
