The eureka effect is a moment where insight of knowledge burst do to the level of your creativity.
when all awareness is focus on one single thought, you can take the tought anywhere you wish in your mind. its almost as lucid dreaming but you are awake(lucid dreaming is awake awareness while your sleeping). Most thought just come and go becuase we dont know how to really keep full awareness on them.
if you focus all of your energy on one single thought, i bet you can guide it anywhere you want.
