How do you know if you're addicted to riddles?
My silky feathers serve a rest,
Beneath a gentle crown of dreams.
The eight hours I manifest,
Is often quicker than it seems.
I am the wool of a sheep,
But I cannot ever be sheared.
I can be found never deep,
Unless when thoughts have appeared.
I am the shield of a mind,
Bringing death to the heart;
I am a sword for pirate kind,
Showing life for a mortal start.
As the present of the past,
I am still, but never idle.
Your mem’ry may not last,
Thus, I keep it with a smile.
I thank the trees as a pencil’s friend,
So pale though never in fright.
In shedding a tear, I will likely bend,
Though eyes only earn my despite.
What do all of these riddles have in common?
There are two answers: the obvious one, and the not-so-obvious one.
HINT RIDDLE: $\;\dagger$
I’m made of glass, this much is true;
But when you look, you won’t see through;
When there is one, I can make two;
Reflect on this to find a clue!
This riddle is not mine.
I will credit the source of the riddle after it has been solved in order to not spoil the answer, for those who wish to look at the hint.It can be found here.
SECOND HINT RIDDLE:
When together, we might have a spine,
On a shelf, though we have not one bone.
Either blank, with a graph or a line,
I'm a sheet with no cotton to own.
The last answer is what I define,
But it might just already be known;
And although I've a simple design,
Via me complex art might be shown.
