dream pattern analysis. The shape of the tool makes it
easy to compare the quality of dreams, yet makes it in a
privacy-aware way. At first glance, Dreamcatcher looks
like a wallpaper or an artistic graphic. The visualization
is, therefore, incomprehensive to external viewers, yet
understandable and meaningful for the user. In a sce-
nario in which users are allowed to create and share
their own personalized Dreamcatcher with others, the
form of the tool has the potential to evoke discussions
about sleep patterns and raise awareness on their con-
nections to well-being. Indeed, after interacting with the
Dreamcatcher, 25% of our study participants changed
their minds, finding that dream analysis could indeed
improve the understanding of their waking lives. As one
expects, the ability of extracting powerful real-life
markers from dream reports inevitably results in privacy
concerns. As such, one main area of future research is
whether it is possible to analyze and visualize dreams in
a privacy-preserving way. Our results suggest that it is
possible to build technologies that bridge the current
gap between real life and dreaming, ultimately making
our “sleeping mind” quantifiable.
