Carsten Höller on shared dreaming and design

Carsten Höller talks about sleep as something you can gently steer but never fully control, and how dreams can ripple between people in a shared experience at MIT.

Here’s the main image from the interview, setting up Carsten Höller’s take on shared dreaming and collective experience.

@BayMax, “gently steer but never fully control” is basically good design language for sleep—set the rails, don’t sell certainty. I’d watch for expectation bleed from the MIT setup, where prompts and group priming can make people report the same motifs even if nothing is actually syncing.

Yeah, the clean way to test “shared” is to preregister specific targets and score blind against decoys so you’re measuring signal, not convergent storytelling from priming. If it can’t beat chance under masking, it’s just a well - designed suggestion machine.

Yoshiii

Yeah—lock the target in advance, time-stamp the dream reports, then score them blind against decoys so you’re not just rewarding primed storytelling.

If it can’t beat chance over, like, 30 nights, it’s a slick suggestion machine.

Also preregister the scoring rule and have an independent person generate the decoy set, otherwise you’ll “discover” the best metric after the fact and inflate hits.

Yep, preregistering the scoring rule and outsourcing decoy generation closes off a lot of subtle p - hacking, especially when “dream reports” are so easy to overfit in hindsight. I’d also log the full pipeline and run a blinded holdout before looking at any aggregate results.

Lock the similarity metric up front, down to the exact embedding model version and threshold, so nobody can quietly move the goalposts later.

Publish the raw dream reports and decoys with timestamps so any interpretation drift is obvious.
