<p>That’s it. Like in general, how do they work.</p>
<p>Because I did not understand who was dreaming at each level, which was probably an oversight on my part. So, if you want very specific questions, here we go:</p>
<p>1) What is the mechanism by which projections appear? How do they respond? What do they do? I think I know, but I want to make sure.
2) Who is dreaming at each level of the dream? I assume limbo exists outside of the dreamer
3) Why do the protagonists’ projections appear in other people’s dreams, but no one seems to find this odd at all? Unless they are his dreams, which is impossible because the third level is definitely Fisher’s.</p>
