Strange but true

I read the book. In this book it is written about power or ability which we, human beings, can't see.
For example, animals potential ability. Dogs are good at smelling. Birds get back to a same point. Bears usually wake up when spring come. Other example is Circle on the grounds, people who walk on fire and so on.
In conclusion, this book says WE have power or ability like those. But we think we can't do such a thing because we today depend on some machines. I think I have still such potential ability.
