I just understood how sytenestesis works. Eg. some colour causes certain mood and some music causes the same mood. The brain is able to connect facts in a kind of reverse way. And that is why while hearing music I see the colour. And that is why I often connect facts that someone would not think of.

And that also makes sense why I prefer the top down level approach to thinking, and also that often ask question in a http://en.wikipedia.org/wiki/Reductio_ad_absurdum manner. Which makes people confused.
