Oh dear... I must say, I hope something like this is banned for recreational usage. Before it hits the market.
Otherwise I'd be worried about creating a generation of the worst addicts we've ever seen, like, WALL-E tier stuff. Powerful narcotics have nothing on lucid dreams, they just normally take work to accomplish. A good bit of it, actually.
Yeah, I thought it was really interesting when the article claimed half of everyone reports one.
The danger is in the accessibility though. If it's too easy, essentially, why wake up? A healthy person probably wouldn't be at great risk, but a borderline individual would be in grave danger imo, of it permanently fucking their priorities up.
There are also books, games and movies that are really engrossing and I find myself feeling very much immersed in. Those need to be banned immediately as well, of course.
