And yeah, the idea is that, well, if I'm just looking at your brain activity, even really vaguely, even with like an EEG, MRI is better.

But if I do this and I just show you a bunch of images and I know which ones you're looking at, over time, I can learn to associate certain activities with certain colors and certain shapes and certain faces.

And you do this 10,000 times.

Yeah, you can start to show the person something and you don't even know what it is.

But you look at the activity and a computer algorithm can go, I think they're looking at a question mark.

Now, on minefield, we looked even a step further, which is what we should be running this on someone's brain while they're dreaming, because then we will be able to create on a computer screen what they are seeing in their dream.

And did you?

Maybe.

Problem is people don't really remember a whole lot about their dreams.

OK.

So you wake them up and you go, were you dreaming about a tomato?

And they're like, I don't maybe.

Yeah, there was something red.

And you're like, oh, maybe we did it.

OK.

We certainly don't know that it looked exactly the way it did on the on the computer.

Wouldn't that be amazing?

It would be cool.

I think one of the problems is that dreams aren't necessarily a movie being played in your head.

I think in a lot of ways, they're a collection of feelings and recollections and information being quite arbitrarily moved around and stored or not.
