2 or 3 years ago I made wings with my imagination and tried to fly off the swingset.
It didn't work and my knee came up and hit my chin. I didn't like spitting blood. But I guess maybe that type of 'creating reality' maybe isn't what you are talking about. I just know that I always used my imagination different since then.
