Monday's Riddle! Under a Veil of Illusion...

Hello Riddlers! It's that time again, so here's this week's riddle. Can you guess the theme? I've been looking for one of these forever ; ) ~ F

Through the eyes of imagination you will believe, though I may be somewhat strange to perceive. Whether it's fire I bring or a promise of youth. See me once, and you'll know the truth. Sometimes I speak, but sometimes not. Sometimes I walk or sometimes trot. Possibly I fly or howl at the moon. Close your eyes, and I'll be there soon. There are ways to find me written in lore-things that will bring me right to your door. But, I can't be seen, and I must stay hidden. For, I am something of a dream; long lost and forbidden. Those that are clever and take time to look will find me lurking in the pages of a book. 

What am I? 

I gave you a clue!
