Surfing my blog archives from a particular time in my life, I came across this one that describes it abstractly, and yet perfectly. 

October 5, 2006… I can see there how it really hit me in a very deep place that hadn’t really been disturbed in a long, long time. There are negative connotations to the word “disturbed” that some of us, usually of the artistic persuasion, recognize aren’t necessarily the case. To be disturbed is usually not a good thing, but sometimes it is an illuminating thing. Revelations happen. Not always nice ones. But it grows you inside. Once you see that, then you find yourself pursuing it from time to time. And people think you’re nuts. And you don’t really care anymore. That day, I was disturbed. And it was amazing.
