What is it like to be back on earth?

When you come back to Earth, you experience some very funny moments. At least in the early missions, in the later missions not as much, you go through moments in where your system does not know where it is. It is still hanging on to spaceflight back on Earth, so you experience floating sensations that are incredibly real because your system is taking you there. It is grasping in some form of reality and in the twilight zone of going off to sleep it lets go again.
