This area continues to be extremely active. Despite some rather notable multi-year crash-n-burn failures on KickStarter (e.g., Aurora and iBand, both of which I followed closely), entrepreneurs just can’t leave this area alone and keep trying to produce and market lucid-dream enhancing masks/devices. I think the success stories (hello? hello? anybody home?), or more accurately, the lack thereof, should be ample evidence that the really only one and true way of generating more lucid dreams is to live lucidly, set strong intent for lucid dreams, and become a bona fide expert on your dreams and sleep.
It may be a cynical point of view, but I see these campaigns as methods solely meant to enrich the founders.
In the best case: imagine there’s a device that can perfectly and every time produce a signal when it detects you are in REM. Lights, sound, vibration, etc. The brain is very very adaptive by nature, and over time, it is very likely that your dreaming mind would incorporate the signals, and basically say “pass!” on the stimulus.
There is just no substitute for grit, dedication, determination, and continual and consistent effort over time. Imagine how far one could have come since 2020 with dedication, now in 2024!
It is a frightening thought to consider all the wasted years. Dreaming and lucid dreaming is one of the most rewarding (and demanding and frustrating at times!) activities in life.
You already know what do to.
