What if emotions, as ideas, are just longing to be expressed?
NEED TO SCREAM
Perhaps emotions are the counter "beings" to inspiration and ideas.
The playful immaterial beings that live inside of us. Floating in the ether, of our inner infinite universe, searching for ways to go out, points and pores to connect with the outside, physical world.
Once manifested, they rest peacefully and we make friends with them. Or enemies.
But if we don't let them out or we don't allow them to manifest outside (by writing, drawing, dancing, performing, laughing, crying, beating up, punching, running) they keep hanging around, lost and lock inside, until they find their own way to come out - perhaps through sudden rage bursts, or they give us physical pain or illness.
