You can't feel movement as such - only acceleration, that is, changes in movement. In fact, movement can only be defined in terms of some other object - "absolute movement" or "real speed" doesn't make sense, physically. In this case, you might say that you are moving with about 1600 kilometers per hour (with respect to Earth's center) or not at all (with respect to the Earth's surface). Or that we move with 30 kilometers per second - more than 100,000 kilometers per hour - with Earth, in its orbit around the Sun. None of this points of view is more "real" than the others.
