Definition Poem

What is a _______?

It takes no shape or form,
And can only be seen by you.

It lives a short life.
Alive at night,
Dead in the morning

Filled with everything that we could ever want
or ever hope for.

It is a place where our imagination can run free
But also a place for our darkest of thoughts.

It can be filled with happiness and joy
But also worry and fear.
