I don’t think that’s geographically possible? We don’t have any really solid maps of how Beleriand connected with Middle Earth, but there would have been a good three mountain ranges and thousands of miles of northern wastes to go through if they’d been connected.
But there are certainly similarities as far as dark, spooky, spidery, Sauron-tainted woods go!
…On an unrelated note, “Taut-UNF-uin” is definitely going to be the name of my new First Age porno.
