• The cards are my wisdom,
    the voice in my head is the guide.
    You probally don't like me,
    and neither do I.
    But be carefull with me,
    because my friends,
    you can't see them
    but they sure can see you.
    Even thought they're invisible
    don't underestimate them
    because they're dangerous.
    You can believe in them or not,
    though all children are scared of them
    and lose sleep at night from fear.
    Maybe they'll visit you as well
    when you're about to sleep.
    Make sure to keep the light on
    cause they can't be seen in the light,
    only in the darkness can you feel their presence.
    ...Can you guess what creatures my friends are?
