Prophetic is developing technology to induce lucid dreams, in which CEOs can practice for board meetings and architects can design buildings while asleep.
If this is the same startup I read about a while ago... Well the technology doesn't actually exist. There's a vague suggestion that maybe lucid dreams could be induced through techniques that are not properly understood yet, and that's about it.
Well FWIW there are somewhat reproducible techniques, I've used them, but I couldn't tell you how I've used them if my life depended on it (honestly, brain chemical imbalances or fatigue might be a prerequisite). I actually got tired of lucid dreaming and started avoiding certain positions in bed, and started shifting around if I felt myself getting close to jumping into a lucid dream during hypnagogia.
I also worked on university assignments during lucid dreams, solved countless bugs in my code while asleep, a friend can even attest to it since one time I instantly woke up to solve a specific bug and then went back to sleep, with him right next to me (all nighters woo hoo).
It can be done. It really shouldn't be done. The reason why I grew tired of lucid dreaming is because I didn't feel like I was actually resting at all. That disconnect and peace that falling asleep gives you, it's not there for me while lucid dreaming (at least not if I jumped in through hypnagogia).
I was often sent flying with no way to come back down. Went up fast. Not great for anxiety. The "focusing on stuff" trick does work, though if I overdid it I also woke up because I tried engaging my senses too much.
