Answer:
I can generate fear and some say I come out of your ears. I am as quiet as a mouse but not welcomed in the house.
Glittering points that downward thrust. Sparkling spears that never rust.

I cover what's real; hide what is true, but sometimes bring out the courage in you. What am I?
What is yours but only used by others?
