Such a beautiful danger stops on your bedroom window and leads to your most private space. Are you a little girl? I think you're expecting love. I can't think of anything more aggressive and dangerous than love.
Cousin usually seems to take care of you and will help you when you are in trouble, so when this "butterfly scorpion" appears in your dream, your subconscious asks cousin to come out and drive it away.
Hehe, it's a lovely dream.
