Answer:
I turn everything around, but I cannot move. When you see me, you see you! What am I?
I am the only thing that place today before yesterday. (one word)
Though I am only two words I have thousands of letters in me
I have a gown but I'm not a priest; I have a crown but I'm not a king.
I am like thunder in your cranium
Though not a plant, has leaves. Though not a beast, has spine. Though many wouldn't need this thing, It's more valuable than wine.
