Think of it as an image closer to what you eye actually sees and also with more detail.
I'm sure it's happened to you, you take a photo and either the foreground, or the background aren't "lit" properly, they just don't come out as you'd have liked or as your eyes see it.
This is the beauty of HDR, it allows a greater dynamic range of luminance between the lightest and darkest areas of an image.
Your camera will take 3 shots at 3 different exposures that you will then merge using a software such as Photomatix for example.
Unfortunately if you search for HDR shots on Google or Flickr a lot will be way over the top, with very unrealistic looks. That's because it can be tempting to push it too far and actually miss the whole point.
Here are a few good examples of mine:
If you look at my older posts, they are full of other HDR shots, you can also check on my website.
I hope this gave you some inspiration, it's a lot easier than it may appear so give it a go and ask me if you need a little advice!
