Histogram Pixels through the roof?

Having read many explanations of histograms I still have one question. What is happening to the pixels that go up through the top of the histogram and disappear? Are there just too many to display and the situation is normal or is there a problem? I know the left side are dark pixels and the right side are light pixels.

It simply means there's more pixels on that particular brightness that the graph has exceeded it's pre-programmed limits. It won't prevent any of that brightness from being visible in the image. It's just a 'fault' of the programming.

Let's say you have 100 people in a room, and your pre-set histogram only goes up to 50. You're supposed to plot people by the color of their clothes. And there's 60 people wearing blue. Just because 60 exceeds your graph doesn't mean you suddenly cannot see those 10 people wearing blue.
