Sweden’s Goteborg Festival runs from Jan 28-Feb 6, and among other things they're gonna try hypnotising an audience.
Says Hollywood Reporter:
After locking audience members in a coffin to test the limits of claustrophobia and taking social isolation to the extreme by stranding a single viewer for seven days on an island in the North Sea, Sweden’s Goteborg Film Festival will use its 2022 event to experiment with mass hypnosis.
At gala screenings for three films at this year’s festival — Apichatpong Weerasethakul’s Memoria starring Tilda Swinton, Shirin Neshat’s Land of Dreams with Matt Dillion and Isabella Rossellini and Christian Tafdrup’s psychological thriller Speak No Evil — a hypnotist will perform a mass hypnosis on the audience, “transforming the audience’s state of mind in accordance with the mood and theme of the film,” organizers said Tuesday. The hypnotist will only break the spell after the screening. (Source)
The trailer for this experience makes it seem pretty wholesome.
