I don't have any examples, but the general idea is that if you have issues that you aren't paying attention to and you start meditating, you relax and become quiet inside, and these issues you've been ignoring start to come up.

For some people, especially if they're previously unaware of their issues, it can seem like meditation itself has caused some bad reaction.

It's like if you're listening to the radio really loud and then turn it off and hear the smoke alarm. Turning off the radio didn't cause the smoke, but it might sound that way if you're not familiar with what's really going on.

One example in the article was trauma, which seems reasonable. Home situations for children vary wildly and I wouldn't expect children to be mentally equipped if they're exposed to abuse, bereavement, etc. Teaching them to virtually bottle up their emotions is something I'd expect to end badly sooner or later.

No one is talking about bottling up emotions.
