You can't truly experience freefall except in a vacuum or in an object that is producing an accelerating force to counteract the force of air resistance (like a really fast elevator, or a vomit comet plane).

The reason is that the air itself is imparting substantial acceleration upon you from you hitting it, which leads to terminal velocity. Once you reach terminal velocity the air pressure is imparting exactly the same kind of force against you to repel gravity as the floor would be at ground level, so you experience one full g. You only really feel weightless the moment you jump off a surface, before you've accumulated any velocity and thus before you're being accelerated by air resistance.
