How are you dealing with deaths of patients?

I'm studying to be a nurse. Today is my second day of practice at the hospital. In a five hours I had to deal with corpses two times. And I saw these people living, breathing. I talked with them. And then you go to the intensive care unit to pick up the body and take it away. It's so… strange??? I can't express this feeling. And they even were warm, when we put them into bags. I always thought corpses are cold.
