In communism, people work together to produce and distribute the things they need to live, such as food, clothing and entertainment. That does not mean that everything is shared at all times.
In a communist society, individuals might still live in their own homes and have their own food, clothing and personal items such as televisions and cellphones. However, the places where these items were produced, such as factories and farms, would be owned by everyone.
Similarly, a person might still create artistic products such as works of literature or craftsmanship on their own. The goal would not be to make money, though, but instead to share for everyone to enjoy.
In such a society, everyone would also have equal political rights and would participate in governance together. Theoretically, communism should entail some form of democracy.
