To be fair, I’m not blind and I’m not entirely sure I “see” things in my dreams. I don’t remember my dreams very often and when I do, it’s more knowing what happened and less images. Then again, I’m pretty sure I’m somewhere on the aphantasia spectrum. But my point is, it’s really hard to tell and thus to study.

Being only 3 to 4 meters deep would make them more dangerous to the average grown-up, I would say. If you jump or fall in, you are much more likely to get hurt. Also alcohol.
