It's only a thing in an extremely high gravity gradient, such that one end of you experiences far higher gravitational forces than the other. This means that while you are in freefall "on average", overall there is a stretching effect as parts of you closer to the source of gravity try to accelerate faster and parts farther away are lagging behind.
