Get ready to head back to ‘The Upside Down,’ because Stranger Things is back!

One of the biggest surprises of this year’s San Diego Comic Con was the debut of the trailer for the second season of Netflix’s Stranger Things, which will premiere in October.

All of your favorite cast members are back, including Eleven, who essentially evaporated in the first season finale.

And, for those of you that absolutely loved the soundtrack to the first season of Stranger Things, it seems the second season’s soundtrack might be even better, because they used Michael Jackson’s ‘Thriller’ during the trailer.

As mentioned above, the second season of Stranger Things will debut in October.
