It makes me nervous to be on him becuase I never know when somethings gonna make a little noise and scare him.
BINGO.
You get nervous, he sees your nervousness, he thinks there is something to be nervous about - it becomes a vicious cycle. You need to break this cycle by being calm and in control yourself, and not get sucked into his drama. Yeah, I know, easier said than done, but it's particularly important with these really smart, really in-tune horses.
About getting nervous, I've learned to breathe deeply, and make 100% sure that your aren't riding differently.
It's not that a horse can read your mind, it's that your body changes when your nervous, you start tightening your legs, etc.
If you're riding and he spooks, pretend to melt your body down to the knees like a chocolate bar in the sun, and contract your calf muscles (make sure not to tighten them around the horse though), and keep them tight until he settles down.
When it comes to desensitizing, how long have you had him?
You need to develop trust before he'll be really calm.
I've seen trainers ask a young horse to walk on a scary tarp, with no previous work working up to that, then whip the horse when he refused. This is
not desensitizing!
He needs to trust you before he will be bombproof.
