While physics defines gravity as a force or spacetime curvature, our personal experience of it is a complex interplay of sensory inputs interpreted by the brain. We don't directly "feel" the gravitational field pulling us; instead, we feel the *effects* of gravity being counteracted by other forces, or the inertial consequences of being in a non-inertial frame. This subjective feeling is often what non-scientists *mean* by "gravity" in an everyday sense – the feeling of weight, the sense of "down," the effort required to move vertically.
