Hmm, that's an intense dream that I certainly wouldn't want to experience. I wonder if Believers are feeling a bit uneasy over the anti-Christian abuse which our society is dishing out, and this uneasiness is reflected in our bad dreams. Just a thought.
Given that the dreams and visions of such needs for hiding fit Biblical prophecies for the end times rather well, I'm quite comfortable taking such dreams etc. at face value if Holy Spirit gives any witness to each one on a case by case basis, at all.
