The recently uploaded ambiguous 44-second teaser of the second season of the hit thriller, sci-fi series "Stranger Things" just adds to the fans' agony of waiting before the first episode officially premieres. The video confuses more than hints the fans of what is in store for them in this show's second run.

The trailer, titled "Nosebleed," flashes photos and clips of rainbows, sunflowers, and the number 450, juxtaposed with some newspaper cutouts and Eleven's (Millie Bobby Brown) bleeding nose. Newspaper articles, with the headlines "Alleged Experiments, Abuse," "Dr. Martin Brenner Named in Lawsuit," and "MKUltra Exposed," give some inkling on the experiments being conducted on Eleven. The video also somewhat enlightens spectators on what the real story behind Eleven's telekinesis is.

A clip of Dr. Martin Brenner (Matthew Modine) is shown in the video as well. Based on these, what can be deduced is that the second season might delve deeper into what happened in the Hawkins National Laboratory. The season 1 of "Stranger Things" revealed that Eleven was a test subject by Dr. Martin Brenner.

What can also be heard is a voice saying, "three to the right" and "four to the left," while displaying arrow signs. This seems that a woman is giving directions to another person. It might be related to the flashes of an unfamiliar woman.

Even though trailers were released, these actually leave more to the imagination, as opposed to the usual conclusion of presumptions after watching a teaser. In addition, a 30-second video showing the new episode titles, uploaded on Twitter, with chapters 7 to 9 being unnamed, were obviously changed from the lineup initially released.

Eleven, Mike (Finn Wolfhard), Dustin (Gaten Matarazzo), Lucas (Caleb McLaughlin) and Will (Noah Schnapp) will return on "Stranger Things" season 2, which will premiere on Netflix on Friday, Oct. 27.
