I can get that sensation once in a while when I'm driving for an hour or so in my car. My brain kinda makes the car an extended part of the body so it's a bit of a strange sensation to suddenly "rediscover" your arms and hands as your actual limbs. First time I experienced it I thought it was because I needed a break from driving but I wasn't even remotely tired or unfocused. I was maybe too much immersed like what happens in VR?
