"Stranger Things" has subjected audiences to several sickening moments over the years, but star Millie Bobby Brown has revealed the one scene that literally made her sick.

In a post to Instagram on Tuesday, Brown shared a behind-the-scenes clip of the series' Season 3 episode "Chapter Six: E Pluribus Unum," in which her character, Eleven, spins backwards repeatedly while telepathically contacting Billy, played by Dacre Montgomery.

While Brown was seen spinning in slow motion during the scene, this dizzying clip shows her on a harness, spinning much faster in real time. She admitted that the scene's repeated spinning caused her to understandably throw up.

She has praised her co-stars on numerous occasions on social media, including a recent on-set photo with Dacre Montgomery, captioned, "One of my favorite people I've gotten to work with. Always so considerate and kind to me while filming some of the toughest scenes I've ever filmed."
