Well, sort of. Think about the sun shining through a lens — it's immediately apparent that the focused spot of light is brighter than the unfocused.

However, the catch is that your "real view" also goes through a lens which focuses the light: your eye. So, in a sense, the real comparison is simply "Is there a lens which is brighter than the human eye?" — and the human eye's aperture is somewhere on the slower edge of fast lenses. No matter how you measure, it's certainly slower than a f/1.4 lens.

But, I think party what you're asking is if a lens can effectively act as an all-optical night-vision device. The catch is that the eye isn't much slower than that f/1.4 lens... probably not much more than 2 stops. That means that the fastest lens possible doesn't really gain that much.

Overall, at least in the context of photography, I think this turns out to be less exciting than it might seem at first. That's because the effect of a an aperture faster than the human eye is only part of the overall equation. We can also make sensors that have higher gain than even the night-adjusted human eye, but most crucially, we can use long exposure to integrate over a much longer time than our own vision does in low light. So, overall, it's really, really easy to produce an image which has an exposure much higher than the scene appears naturally.
