In 2021, an international study showed that two-way communication between a lucid dreamer and a researcher in the lab was possible. In 2024, another study built on this by training lucid dreamers to control a virtual car from within their dreams. The 12 dreamers in the experiment made slight muscle twitches, which sent a signal to a computer to make the virtual vehicle move forward or turn.
Mark Blagrove from Swansea University thinks dreams were meant to be shared socially and evolved in humans to enhance emotional intelligence and empathy. Since 2016, Blagrove has collaborated with artist Julia Lockheart in a dream discussion and illustration group. An audience member is invited to share a recent dream. Blagrove leads the discussion, while Lockheart sketches an interpretation of the dream onto the pages of Sigmund Freud's book The Interpretation of Dreams.
