I feel like these exercises are going to be fairly difficult for someone who doesn't have any experience with their dreams. I've had a few LDs and for me it's pretty challenging to convince myself or get in the right mindset of things being dreamlike, but I guess maybe with practice it would get easier. It's pretty disorienting switching back and forth between reality and "dream" but I think it's a neat exercise. I'm curious though what exactly these exercises are supposed to do to help with LDing? Maybe you could explain that a bit more to expand the chapter some, unless it's something that will be explained in the next chapter.
