Why is it that the moons gravity is able to direct masses of water in different directions but yet we, ourselves cannot physically feel the affect of the moon's gravity?

Tidal forces are essentially due to the *difference* in the gravitational field between two sides of a body. If you consider the difference in the moon's influence between our head and our feet, it is essentially null. If you consider the difference between one side of the Earth and the other, it starts to become significant.
