Blowing Candles

My house was haunted, so I found a master to help me. The master said that to stay safe, I needed to follow these four rules: 1. You must not blow out this candle used for exorcism, or you will die. 2. You are the only one in the house; do not respond if anyone calls your name, including me. 3. Even after tonight, never turn off the lights at night, or you will see ghosts. Indeed, I safely passed today, but I died a few months later.
