Synesthesia is quite interesting. As I've understood it, however, it isn't a conscious choice, but is an involuntary response by the brain to certain stimuli. In other words, there is a difference between synesthesia and imagination.
I experience synesthesia to a degree when I am in a euphoric mania. I cannot "make it happen", and I can't control it. It's so beautiful and magnificent! It is something I greatly miss because medication makes it go away.
