Three beds, arranged in a gleaming, sculptural, Y-shaped aluminum apparatus: They invite you not just to lie down but to surrender to suggestion, hovering at the edge of consciousness. You climb in, and once settled, a choreography begins—colored beads of light gently dipping and soaring, subtle pulses of sound, an almost imperceptible twirl of wands above. You feel your body respond before your mind has fully caught up.
The experience is disorienting, intimate, and utterly compelling. For a few suspended moments, the line between wakefulness and dreaming blurs, reminding us that perception is pliable and that science, when dressed in light and sound, can feel like pure magic.
Titled Hotel Room #2: Communal Dreams, this immersive sleep and perception installation by German artist Carsten Höller proposes the inconceivable—shared dreaming—while tapping into a cultural moment obsessed with tracking the body and measuring and optimizing even our most private of experiences.

And it happens to take place in a museum gallery. It was created in Cambridge for the new MIT Museum exhibition “Lighten Up! On Biology and Time” (on until August), which traces the rhythms of life itself: circadian patterns, light’s command over the body, and the delicate architecture of alertness and rest. Vital daylight, the body’s clock, and sleep cycles converge across 18 works that blend science and art, from immersive soundscapes to visualizations of circadian patterns and reflective spaces where you observe your own heartbeat and alertness in new ways.
In Hotel Room #2: Communal Dreams, Höller’s goal is to explore whether dreams—usually private and uncontrollable—can become guided and communal. It draws on emerging research suggesting that dreams can be influenced in real time by sensory cues such as light, sound, and motion. The programmed sequence of stimuli—pulsing colored lights, spatialized sound, and subtle atmospheric effects—is carefully timed to influence the transition from wakefulness toward sleep and to potentially steer dream content.
Participants often report a liminal feeling—drifting between alertness and sleep—rather than fully falling asleep during the short session. Yet even without sleeping, the synchronized motion and light create a strong sense of altered time and bodily awareness.
Indeed, the pre-sleep state is paramount here, as MIT Museum Studio director Seth Riskin explains in his lab, directly under MIT’s Great Dome in the heart of the campus. “Carsten says the experience is the material he’s working with,” says Riskin, who collaborated with Höller and dream scientist and MIT alum Adam Haar Horowitz on Hotel Room #2. “All the attention is on the conscious experience, but it’s this semiconscious experience that is the artwork. Because of the unusual character of the environment, you can’t help but pay attention to that, but you start losing conscious control, losing a sense of time—it morphs into something else. And once you start drifting off, that’s the thing this is all about.”
