I have some of the craziest, most random dreams about all sorts of weird situations and creatures, so I get a lot of my inspiration from them. Even my first novel (I was 19) was a psychological thriller and I had this girl stuck in my head. She was in a dream and I didn't forget about her until I was able to get her story out.

And that's the thing, too... if a story wants to be told, it will find you. Stephen King (On Writing) compares writing his novels to excavating fossils from the ground. It begins with a tiny discovery... then eventually another detail seen, heard, or read about catches your attention. Before you know it, you've got a basic plot in your head and have to let the characters take you on their journey... ideally, this is when you sit down to write the first draft =).
If you need inspiration, just pay attention... there are things going on all over the world that could inspire you, not to mention your own original ideas waiting to be drawn out of reading or seeing someone else's ideas.
I find inspiration in stories about rare things, too. For example, there's a tree that grows exploding fruit. Weirdness! Just browse online and I'm sure you'll find a lot of stuff that has the potential to resonate with you when you combine it with one or two more elements =).
Good luck! This is what works for me... dreams and elements of real life. You can manipulate whatever you come up with... that's the beauty of fiction! =)
