I realized that the dream “screen” (that is the visual area where dream images appear) is based upon a small part of the whole phosphenes field. And, you’re right, you’re more likely to be dragged into it, i.e. the zoom function seems to be autopiloted.
Xetrov and I have exchanged our points of views on this issue in this post:

It’s very hard not to fall asleep when these random thoughts begin to appear. The easiest should be to loose consciousness and reach lucidity again just after that. I know that some dreamers can make a RC in these conditions. But, as I have never reached this state, you certainly know far better than me what is possible to do or not!
