I wonder how far neural engineering has come. From what I’ve read, it’s as simple as carefully watching what goes in, observing which neurons activate, and using it to reconstruct any kind of perception. I’ve read that, even though it’s likely decades away, it may be possible to tap into the ‘video feed’ of a dream. And this is all from a book written in 2018 . . .

While I would love to know of technological means to force a vivid dream of a certain topic, there is certainly a natural purpose to dreams. Treating a lapse of subconsciousness like an untethered brainstorming session might be a dangerous venture.
