Horses will hold their breath if anxious, so that may be what you are noticing.

So many people set off fireworks last night, and we got almost 20 inches of snow over night. The snow was just starting to fall off the roof when I got to the barn. By the time we were even in the aisle, Fiona was spooking. I took her into the arena and she was spooking at everything. We decided just to lunge her today, and she started to calm down. I'm glad I decided not to ride. I'm almost positive I would have fallen off at least once :/

After lunging her, I rode one of the lesson horses for my trainer, just to get a good ride in during some scary noises, as she's usually ridden by the newest riders. She spooks in such a completely different way than Fiona. Fiona just bunches up and explodes, while the lesson horse just spins around and takes off at a trot. She almost got me off a couple times, since I wasn't sitting back enough when she spooked. If you sit really far back on Fiona, when she takes off you fall over backwards or pull on her mouth to keep yourself on.

Dream Weaver- Thanks so much for the tip on talking to control your breathing. It actually helped a lot! When was talking, she actually spooked a lot less. I think I was tensing up anticipating the spook.
