I didn't know the first thing about Dreaming. 
Sure, we all dream.  Twisted in sweaty linens or clutching a pillow around our ears, usually.  That's the bad dreams.  But Dreaming, so I found out, is a little different.  That was the best name they had for it, I guess.  Other names were too tedious or weren't elegant enough.  I didn't make the rules.
My name isn't Tracy, either.  But it helps me to tell my tales if I'm just a wee bit annonymous.  It doesn't make them any less fetching.  Most of the time, I'm not even Tracy in my dreams.
