Yea. as a kid I could look at something for so long without blinking that the object becomes sharper on detail and a sort of greyish black aura or halo around it and then feel like I am floating. My favorite activity was sitting next to a sit and spin and spinning it because of the bright colors blending into a neat spiral that if I stared at it this would happen, I loved spinning quarters too to do this. Today the objects I stare at don't have to be moving. It could be a crack on a wall or the tv, basically anything will allow me to fade off into that hypnotic state of free floating, far away feeling.

Yes it does work doing it on purpose at least for me.
