Being Agnostic doesn't make you religious. It is not a religion. Agnosticism is simply a state of mind. It is not knowing everything. There can be agnostic atheist, and even agnostic Christians. Atheism does not say you have to follow nothing. It is simply a denial or lack of faith in a god or deity. In fact, Christians are atheist. Hindus are atheist. Why? Because they don't believe in one another's god/gods. Christians are atheists when it comes to Krishna, Bhrama, and Vinshnu, and vice versa. I've known atheists who believe in atherial beings, like ghosts. I know atheists who believe in an afterlife. In fact, most Buddhists are atheist. They still believe in an afterlife.
