Banshee

That's a Banshee. 

A Ghostly Woman in Irish Folklore. 

At the Moonlight, the Banshee 

wailed and mourned when she flew past, 

crouched beneath the Trees, lamenting with veiled Face, 

and she must be seen at Night as a shrouded Lady. 

I think the Banshee was not real, 

she was a just a Fantasy. 

Which means Fantasies are not real.
