Different people get different things out of the images. It doesn't matter what it's about, all that matters is how it makes you feel.
I personally don't like to use as many effects because when you play live, something always goes wrong.
There's always the influence of music, film, art and the other things that drive me. I'm usually inspired by my environment and whatever is making me happy or mad.
