I normally wouldn't weigh in here, since I am the furthest thing possible from an expert, but after even a little dabbling in meditation I can see some major misconceptions in the other comments. It isn't about being bored, or about any of the benefits that may or may not occur. Meditation is a useful discipline because it is about training the mind to (a) become conscious of and "reify" individual thoughts and sensa…
In regards to (a), isn't it more about not reifying your thoughts and sensations? This might be semantics though; I do agree that the path of not becoming a slave to thoughts and sensations starts with acknowledging them.
The rationale being that repression is a short term band-aid that does not allow for resolution of the issue, and can also be a way to conveniently trick yourself into ignoring important things (which you might want to be considering / processing). On the other hand, you also don't want to get further into the emotion, as it may add fuel to the fire (like getting carried away with stories in your mind about what you should have responded with during an argument, etc). So, there's some kind of balancing act there.
So reify might actually be a good word, although it may go to far, as you pointed out.
