Fregna is a synonym of the word Fica or Figa, and it literally means vagina.
We usually use it to refer to a very beautiful woman, it exists also the word Fregno, which is used for handsome men.
It's largely used in central part of Italy.
Ammazza che fregna! = Wow, what a beautiful woman!
Synonym for fica, fregna is the most vulgar Italian term to indicate a vagina, and indeed rather similar to the English word cunt.
It is often used together with the adjective "dry", as in "dry cunt", in Italian: "fregna secca".
The reference is mostly metaphorical in this expression, so usually not to a non-lubricated vagina, but rather more to a woman who is boring, rigid, uninspiring, no fun, skinny and wrinkly.
