The fourth season of "Stranger Things" preview has a slightly scary atmosphere

The fourth season trailer of "Stranger Things" has been released, and the pictures and music create a thrilling and eerie atmosphere.

These images seem to be the memories of the super-powered little Eleven when she was imprisoned in a special government agency as a child. The villain Doctor "returns" through flashbacks, and at the end, little Eleven's rough breathing shows her uneasiness about these painful memories and her eagerness to get rid of them.

The fourth season of "Stranger Things" will be broadcast on Netflix in the second half of this year, with 9 episodes released at once!
