REM-Dreamer has now a new method of induction lucid dreams.
It uses bi-directional communication between sleeping person and device. It is a kind of feedback.
You can read more about it on their site. please no links to sellers, read the guidelines
On first glance that seems new and improved, on second thought, it sounds like the basic premise of eye movements telling the machine to flash the lights. On third thougt it must be something new after all.
Ok, so I googled and read about it. That sounds pretty cool.
In case others don’t feel like googleing, then new method allws the user to signal the device with eye movement signals to set the cues. So if you become lucid you can tell the REMdreamer to not que anymore while still dreaming.
