Lucid Time!

Whenever my dream recall fails, I've made a habit of going back into my memory and recalling dreams that I've had long ago but never written down. Well, here are some of those.

Secret Hardware Store
I probably had this dream about five years ago. For some odd reason, although the dream is not very interesting, this dream tends to invoke a "dreamy" feeling in me.
I recall the location very vividly. I had a sort of internal compass telling me what direction was what. There is a large square clearing in a forest aligned perfectly with the cardinal directions. The clearing is about a half mile on edge. There was a freeway bisecting the clearing north-south, but bearing slightly to the northwest. There is a road perpendicular to the freeway overpass bisecting the square clearing the other way. There are on/off ramps connecting the freeway and another service road running along the western side of the freeway. In the southwest corner there is a large brick building. The grass in the clearing is short, but looks somewhat dead or dried out. The trees surrounding the clearing seem to have either died or lost their leaves for winter. There are a few scattered circus clouds but the sky is mostly a clear pale blue. (Sorry for the long description, don't feel like drawing any maps today.)
I was sort of floating, and I actually got into a half-lucid state for a moment, but fell out of it.I floated down and went into the back entrance of the building, and my body materialized. that actually turned out to be a hardware and electronic components store. Somebody, somewhere was explaining to me that this back room of the store sold specialized components, some of them were not entirely legal. I was given a large sum of money only valid for this store, and was allowed to purchase anything from the back room.
Having little-to-no knowledge of electronics I simply grabbed random components that I found visually appealing. Integrated circuits, batteries, motors, capacitors, etc. I approached the counter. (The secret back room had its own counter and check out.) The man at the counter (can't recall exactly what he looked like.) But the interesting thing that I do recall was that on the counter, half buried in a pile of discarded components was the chip from the AI theft dream that I had years later. But the chip was not glowing as it was in the AI theft dream, but it rather was black as thought it were either inactive or burned out.

Going Deep Underground
This dream feels more recent, but has to be at least a year old.
I was with my ma and pa, along with my deceased set of grandparents. We were in the basement some old dusty building that was filled with storage containers. Everyone but me were simply sitting and talking about eventually moving the storage containers out of the room and renovating the space. I simply decided to explore and see how far this place went.
I found another door behind some shelves that led into another room that felt like it was even deeper underground. There was more storage of boxes on shelves here, but this place looked even older. The walls were covered in mold and the dank, dusty smell was overwhelming. I pulled one of those chain light switches that hung from the ceiling to get light into the room. The room had a wooden floor. There was also some large machine, like a heater or boiler grumbling in the center of the room.
I proceeded further into the room and found yet another door. This one was like a large steel vault door, as if this were a bomb shelter or something. It was covered in rust. I pushed it and found the entrance to some underground complex.
As I proceeded deeper and deeper into the underground, The plot of the dream began to morph to a sort of post-Apocalypse survival situation. I began to hear blasts above and the plot changed in my head. There was a nuclear war going on on the surface and the blasts were slowly penetrating deeper underground. I completely forgot about the basement renovation plot with my relatives. My goal was to get to the lowest level of this complex possible to have the best chance of surviving the war.
I continued down through this complex, and the place was huge, I must have gone down at-least a mile underground, and the machinery was big too. There were huge metal pipelines, as big around as houses, concrete pylons and deep mining shafts that stretched down for miles. The whole place was alive with the humming of machinery.
As I went deeper and deeper underground, the complex actually started to get more polished looking. This was somehow explained to me as the deeper I went underground, the more well-preserved the place was. Before I knew it, the entire place looked completely brand new. Eventually, I arrived at a door and opened it.
I was in a very nice classroom/lecture hall. There were three or four teenagers dressed in power ranger costumes.
From what I can recall, the teenagers seemed like jerks and they didn't seem to like power rangers either, they were wearing the costumes to ironically celebrate the show. They actually started to bully me, but because they were such jerks, I just continued without much of a care, and they did not follow.
The plot of the dream changed again, I and as it turned out, the underground complex that I had blundered into was in fact aperture science. I acquired a portal gun and GLaDOS began instructing me to complete tests with it. I lose the dream here.

Drowning a Bully
This dream feels very recent. I identified Lia in it, so it must have been after I learned who my dream guide was. And the only reason I recall it was because I was writing about the jerk teenagers in that last dream and then remembered what happened in this.
So anyways, me and her are at this waterpark just chilling out and talking. (Because I can be talking with my dream guide as if she is a familiar person and not be lucid. Dream logic strikes again.) we are sitting on the edge of this very large wave pool where there is an underwater bench like you might find in a hot tub.
We decide to make our way back to the pool deck to meet up with [god knows who], and because we are near the back of the pool and start swimming back. We get about ten feet when we run into this group of bullies. Come to think of it, they were exactly like the bullies dressed as power rangers. Now whatever they said, I'm not going to repeat. Not because it was overly offensive. I just don't remember it. So they delivered a couple of pretty vicious insults to both of us, but one of them tore it, and thus began a blood-lusted fight in the pool.
I went straight for the head bully and we traded a couple punches. (BTW this guy was really muscular and much bigger than me.) His punches don't hurt and he notices that I seem invulnerable. (Even though I wasn't lucid.) He attempts to shove me underwater and drown me, but I hold my breath until he allows me back up.
I lift up my legs in the water and wrap my legs around his body, then twist and rotate so he is underwater. He pushes me down with his arms so neither of us can breathe. He can't get out of my leg lock, and I can breathe underwater so the head bully ends up drowning. I come back to the surface, and Lia and the other bullies are gone. The head bully is dead and there is a little bit of blood in the pool.
A lifeguard swims over (Oh, hello, where were you earlier?!) and is really angry with me for killing this guy. The lifeguard has called the police and will have me arrested.I have the vague feeling that killing this dude was really no big deal, and that there are really no consequences to what has just happened.

Fragment
Something going on at my grandparent's house. (My grandparents that are still living.) Don't recall much but it's giving me a dreamy feeling and it was summertime. The area eventually began to merge with a tropical rainforest setting. There was a tree that grew over their deck with pear-like fruits on it.

Umbrella Flying
I have no idea who Mary Poppins is or what it's about. (Is it a show, movie, what? All I know is that some woman flies around with an umbrella. Perhaps a commenter can give me some insight.) But when I told my friend about this dream, he said it reminded me of her.
This was actually a recurring dream that I had as a kid, but one occurrence in particular is just speaking to me right now. So the setting was rather usual for my dreams, I was above a forest. But the thing that I recall was that this forest was a gorgeous, vivid shade of green. The sky was cool too. It was very dark and stormy with layers of storm clouds. The colors of the clouds were vivid too. The forest actually grew on some very mild mountains and small rivers ran through the valleys.
I was clinging to this umbrella, both thrilled by what I was experiencing and terrified at the thought of letting go and plummeting half a mile to my doom. I seemed to have some type of control over how I flew and what direction I went, but for the most part, I felt as though I were at the mercy of the wind. I also recall also feeling the temperature and wind. Cool. I felt as if I were getting wet each time I rose up into the storm clouds.
Eventually, the umbrella began to lose power and I slowly drifted to the ground in a park-like area. I encountered my family there, and it seemed as though some sort or arranged meeting with my parents was taking place. I continually opened and closed the umbrella in an attempt to catch more wind currents and begin flying again, but I only managed to catch increasingly weak breezes that led to shorter glides until the flying method failed entirely.

Foster Home
Another dream that feels rather old. Probably from before I began lucid dreaming.
My parents had been killed and I was surprisingly OK with it. Maybe I was in a state of denial, or maybe I was partially lucid. I had been taken into a foster home and was experiencing my first day with the other kids.
First of all, this foster home is really weird. It looks very high tech, the walls are made of sheet metal and have these high tech lighting conduits along the floor and ceiling. It feels like the place is underground.
Basically there is a main hallway with a doorway at one end. On either side of the hallway are two large square rooms, one after the other. The first room on the left is a playroom, where the kids keep their toys, and the second one is a bedroom. Most of the kids sleep in hammocks, rather than actual beds. (due to space constraints or personal preference, I don't know.)
I don't know what was in the two doors on the right. It's safe to assume one was a restroom.
Anyways, I was being introduced to the place by my foster mothers, one of whom seemed very stern and strict, and the other more kindly and playful. They briefed me on how to act around the other foster kids, and also explained to me that since I was the oldest, I may have to supervise the younger ones when the foster parents are not around. They eventually left for me to get acquainted with the other kids.
At first the other kids did not seem to take very kindly to me. They harassed me for being older than all of them. But we eventually wound up in the play room and broke out into a rather large Nerf gun battle making use of the main hall, bedroom and play room.
