i can't hear it, but i can imagine the thump as it hits the ground.
there was an interesting documentary a while back about the subconcious and what it does for us, like for example a lot of what we think we see is in fact just a construct of our imagination that's built up from previous experiences, it's the explanation for things like not being able to find something even when you're looking right at it (if your brain is imagining it to be somewhere else) or seeing ghosts in terms of things appearing in our peripheral vision that we don't expect to be there.
