You're pouring yourself in a casket

Was thinking about the afterlife.
About the mind out of control.
You're pouring yourself in a casket.
Like the fish in the ocean.
But when we look at it as humans.
that there is more on the horizon.
The Earth, but also the universe.
outside of the ocean.
We are the fish in this story.
The unseen world of the afterlife.
is like the oxygen on Earth.
Like the universe in different layers.
