When you are doing something alone at home at night, don't forget that there is a pair of eyes staring at you.
At twelve o'clock at midnight, it will make you feel even more creepy. Maybe you will boldly comfort yourself and say: all this is fake. People who are afraid of ghosts just have ghosts in their hearts. This is just a psychological effect.
But let me tell you, ghosts do exist.
Because I've seen ghosts, ghosts are all around me.
Maybe, I am a ghost...
