Last Saturday was a very strange day for me. First, I got up at 1 AM. Then, I went downstairs to take some drinks. I was drinking water when, suddenly, the phone rang. "Hello?" I said. No voice, it was just a breathing sound. Very heavy sound! "He-hello?" I repeated. Still no answer. I immediately hung up the phone and ran back to my room upstairs.
What is the possible paragraph to continue the story?
