Someone who has never seen Black Mirror wants to make lucid dreaming 'the ultimate VR experience' with dubious tech

pcgamer.com:

Lucid dreams are defined as the experience of knowing you are dreaming while you are asleep, and can range from the sublime to the genuinely terrifying. According to the CEO of new startup Prophetic, its latest project aims to «detect when dreamers are in REM to induce and stabilize lucid dreams» via a wearable device they call «The Halo». And if that doesn't sound like a cyberpunk future developing in front of our very eyes, I'm not sure what does.

Vice's Motherboard recently interviewed the CEO of Prophetic, Eric Wollberg and CTO Wesley Louis Berry III about this project and the ramifications of such a potentially world-changing technology. Prophetic has recently entered a partnership with the Donders Institute, a research centre for neuroscience and cognition based in a university in the Netherlands, and this has allowed the company access to a huge dataset of electroencephalogram (EEG) and functional magnetic resonance imaging (fMRI) observations of people who lucid dream.

This data is being used to help research and develop a technique referred to as «transcranial focused ultrasound», or TUS, which is designed to use «focussed ultrasound processes» through a wearable device to tell when the brain is lucid dreaming. The company hopes that the development of this technique will eventually allow the device to interact with the wearer's neural activity and induce a lucid dream on-demand. 

Wollberg and Berry are quick to tout the supposed benefits of lucid dreaming, from helping with PTSD all the way through to inducing an experience that sounds remarkably close to gaming. «You can fly, you can make a building rise out of the ground, you can talk to dream characters, and you can explore». Blimey.
