Anglo Saxon Riddle

Riddle #1
 Of trees sons, I am by your side,
Thoughtless thoughts I can hide
Life quandaries I help solve,
My importance grows as the world revolves.  
Shape shifting powers that do not bore
 Darkening substance lies within my core
A helping hand to those in need,
Dreams, thoughts, and fantasies flow free

Bonus riddle: Just for fun.
Riddle #2
Behold the world’s undying beauty
Let me show you as it is my duty
Latches on two sides keep me in place
Smeller of scents is what I embrace.
