In spring 2026, the Schering Stiftung will present Rehearsal Room, an exhibition by Berlin-based Chilean artist Nicole L’Huillier. The title Rehearsal Room refers both to a space for practice and to a particular kind of acoustic environment. Using sound, artificial intelligence, and voices, L’Huillier transforms the exhibition space into an experimental zone. Upon entering, visitors are invited to collectively tune into the realm of dreams – as a form of another reality. The sounds are selected and arranged to affect visitors; their brain activity and heartbeats resonate with the tones and frequencies in the room. This results in a threshold and synchronization space that offers both tranquility and retreat, allowing visitors to engage in new physical and cognitive experiences. To create this soundscape, the artist works with digitally generated sounds, sound frequencies, human voice, and field recordings, thus entangling natural and composed sounds with others created by artificial intelligence. The exhibition was developed in close collaboration with dream and sleep researcher Dr. Adam Haar Horowitz, who specializes in dreams and dream incubation, with a particular focus on so-called hypnagogic images ­­– vivid mental images that emerge as one falls asleep.
