Answer:
I am the type of room you cannot enter or leave. Raise from the ground below I could be poisonous or a delicious treat.
I have memories but none of my own whatever's on my inside is what is shown. If I'm ever different it's because you changed me I feel like a decoration here for you to arrange me.
Everyone has me except for a few. You may not be able to identify me but I can always identify you. What am I?
Without me everyone would lose their head.
Fatherless and motherless. I was born without sin roared when it came into the world. But I never spoke again.
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.
