Answer:
I'm the source of all emotion but I'm caged in a white prison.
I am milky white and scares people.
I sleep by day, I fly by night. I have no feathers to aid my flight. What am I?
I am enjoyed by some, despised by others. Some take me for granted, some treasure me like a gift. I last forever, unless you break me first. What am I?
I am a busy worker who is a water mammal.
It flows out of the soil, It burns you if it boils, And holds us in its coils, More valuable than gold, As black as it is old.
