Actually, your English sounds quite good!

Anyway, just because you may be aware you're dreaming, doesn't mean you can't get scared. I sometimes have nightmares that are lucid, and I'll get so freaked out that I have to wake myself up. Being lucid and actually being able to control your dreams are two different things.

For me, becoming lucid is just a part of my dreaming - I'm almost always aware that I'm dreaming. It's the controlling part that I sometimes have difficulty with. Like sometimes I'll want to fly, but I just can't get off the ground high enough - so I have to tell myself, "this is MY dream, and I can do whatever I want in it, and nothing is holding me back", then I'll be able to do it fine. It's like I have to overcome my own barriers.
