Cravings

Not sure if this is the right place for this post!

My friend is having a rather unusual craving while being pregnant, she finds a petrol soaked hankie comforting to smell? I had cravings like fish, cherries and strawberries which makes my cravings look and sound boring in comparison! I've often heard people say that cravings occur as you are missing something in your diet, but what purpose does petrol or even soil have? What cravings did or do you have?
