Yeah, it's important to point out the difficulties that can arise. Though I'd say that the framework could also cause problems if your experience falls outside of it.

I had an experience along these lines when I was 22 and meditating daily, which ended up turning into anxiety and somewhat frequent panic attacks. I ended up giving up my daily practice for about 10 years because of it. My frame of reference was the very common Theravada practices you encounter in the west, but my experiences didn't make sense to me until I began reading Mahayana teachings and found my way to Vajrayana practice.

So I'd say the framework is important, but to be flexible with it as you encounter things that aren't maybe a part of the core teaching. In my case it was the teachings on emptiness that opened things, which is something the Theravada doesn't emphasize (although it's there).
