Cities in the Astral

I tried just observing again. I was in a Home Depot store and seemed to work there. I just watched. Here comes something weird as hell. A woman has a baby that walks upright, but it is kind of a cyborg baby. Its legs are mechanical and thin, and its head is covered with a weird cyborg helmet. She tells me she needs to buy an exercise machine. She points over to another part of the store. I get down and examine the freaky cyborg kid.
I loose my semi-lucidity for a couple minutes and become a character in the dream. I walk over to the exercise machine and demonstrate it. I would say I lack any lucidity for a minute. A coworker is trying to take the sale from me, and we work on commission. I tell them not to ring it up. A male DC starts to yell at me that I am trying to steal money.
I become lucid again and decide this is stupid. I tell him to keep the sale as I could care less.
I leave the store and try to fly, but I am affected by gravity. What? I see a couple DCs and interact for a moment, then I try to fly again. It is like a super hero jump and I just miss getting on top of a taller building. Ok, wait a minute. Why would I have any trouble flying unless I was astral? Hmmm, I will relax and truly believe I can jump up on top of that building. I get up there and the edge moves back away from me. I try again and can not get above the edge. I grab the edge with my feet and am about 3 stories up. I wedge myself against some artificial boundary and the lip of the roof. I examine what is keeping me from going higher. I can see a grid work of energy criss-crossing like the edges of the holo-deck. Wow, it has been awhile since I ran up against the outer boundary of an astral realm. This place must be tiny! It has a ceiling at only 40 feet or so. I wonder how I ended up stumbling into this place? The dream ended before I got any kind of answer.
