jessie little doe

I found it almost unbelievable that jessie little doe started to have weird dreams and realized she was the one to bring back a language that had not been spoken in 7 generations. It was pretty cool how she connected the language that was spoken in her dreams to the street signs she passed one day and followed through with the research.

Since we only use about 10% of our brains as humans, to my knowledge, what does the other 90% do? From what I have learned in the past, there are electrical waves running through our brain and I believe it is possible and almost inevitable for one of the sparks every once and awhile to jump over to a part of our brain that we never use. They do say that if we were able to use all of our brain power that we would be able to walk through walls, fly, and move objects like John Travolta did in that one movie he did in the 90's (I can't remember the name). I realize that I am going a bit off topic, but what I am trying to get at is that I believe that it is possible that jessie used a different part of her brain while she was asleep to understand that the people who were speaking in her dream were speaking her ancestor's language.
