Yume: Dream in color. Wake in clarity.

🌙 What inspired us

We kept noticing the same gap: the people who need emotional  support most are exactly the ones who can't access it. Journaling  requires insight you don't have yet. Therapy requires language you  haven't found. Meditation requires stillness that feels impossible.

Meanwhile, every night, the brain is doing the emotional work the  waking mind avoids — processing stress, grief, and unresolved  feeling during REM sleep. That data has always existed. No tool  had ever tried to read it.  

Yume started from a simple question: what if it could?

✨ What we built

Yume is a biosensor sticker and companion app that captures  emotional patterns during sleep and surfaces them each morning  in a way that's gentle, honest, and actionable. The sticker reads  brainwave activity at the temples. EEG data is processed on-device  overnight, converting raw neural signals into an emotional landscape  — not dream narration, but emotional texture. How you actually felt,  not what happened.

Users wake up to a Morning Reveal: a feeling, a color, and one  optional prompt. They can go deeper if they want — or just absorb  it and move on.  

We also designed three delivery modes (Gentle, Standard, Deep)  so users control exactly how much they see, and when. Because  emotional data isn't like a step count — it can surface things people  aren't ready to face, and we took that seriously.

📝 What we learned

Designing for emotional safety is harder than designing for  engagement. Every decision — how a word is phrased, when a  prompt appears, how much data is shown — carries real weight  when the subject is someone's inner life.

We also learned that people deeply want this. 85% of our 27 survey  respondents said they'd want insight into emotional patterns in their  dreams. The demand is there. The tool just didn't exist yet.

🎯 Challenges we faced

The hardest design challenge was information delivery: how do you  surface something as sensitive as subconscious emotional data  without overwhelming or destabilizing the user? The delivery modes  system was our answer — but getting the language and UX right  took many iterations.

Privacy was also a core constraint from day one. Neural data can  reveal mental health conditions, trauma history, and emotional  vulnerabilities — often before the user is aware of them. We  committed early to local on-device processing, full user data  ownership, and zero monetization of emotional data.

👩🏻‍💻 How we built it

We used Figma for our UI/UX design & prototyping and Google Forms to conduct our user research survey.

🤍 A special thanks

We would like to give a huge thank you to Figma for hosting and Joanna Chen for all the support! We would also like to give a shoutout to our family and friends for their moral support and for helping us with our research! :)

With love, Cindy Chiang & Trinah Maulion ⋆˙⟡♡
