Would it be possible to make a lucid dream headset and would it replace vidya? Basically you put it on your head and during sleep it hits your brains with some electromagnetic waves or something like that and makes you aware that you are asleep and either prevents you from immediately waking up or prolongs it, letting you lucid dream.

I've always been curious about this. Doesn't sound like a crazy concept all things considered. I hope someone is making it.

Hell, just something that would make your dreams more vivid would be cool.

I feel like dreams are an untapped entertainment market.
