Instead of saying "I want my next job to be X", it's "I wonder what my next job will be". Instead of saying "I'm taking a walk to place Y", it's "I wonder where I'm walking to". Of course I can tell myself a destination, but statistically, I know it's far from certain. Looking backwards, instead of saying "You should have said hi to your neighbor", it's more like "I wonder why I acted that way". And it's not always in the direction of being helpless. Sometimes it's "I wonder why I'm exercising so much today".
At one point today, walking, I thought "I'm moving my left foot, I'm moving my right foot, my foot is touching the ground, it's weird that I don't usually think about this". That's meditation-ish, like watching the breath as a swinging gate, appreciating a normally automatic process for a bit. In my opinion, this goes beyond just breathing and walking, and extends into processes like writing and talking - words just kind of come. You can revise them and slow them down, but if you can step back, you might feel words just coming out of nowhere. Sam Harris, mentioned by others in this thread, has also described speech as being surreal in this way.
