I had a long LD last night, possibly my longest one ever. To top off my excitement from such a long LD, I also accomplished a few tasks. 
The beginning of the dream where I became lucid is fuzzy, but I think a full length mirror that only had a sliver of mirror at the top triggered my lucidity. I eventually decided to travel through another mirror, and when I entered it, I hit some kind of black solid back to the mirror, blocking me from going anywhere. This was not acceptable to me, and even though I was afraid the dream might end at this point, I started to kick at the black solid backside of the mirror. While I was in the mirror kicking, somehow I miraculously was able to reach my legs around the top of this backside to the mirror and get it so my feet where on the other side. I then used my feet to propel me off of the backside and through the other side of the mirror into a completely new environment. As I came out of the mirror, I noticed I was falling to my death and that there was a snowy cliff/mountain side where people were standing, but at my current momentum, I wouldn’t be able to land there and I would instead fall to my death.
Fortunately, I was in Captain America’s costume. I also had his shield, so I threw it to knock a few of the people down that were on the cliff side. I’m not sure if I lost lucidity for a second, or if it was just really low level lucidity. I may have thought I was Captain America, but I’m not sure. I know I thought the people on the cliff were evil. Either way, after I used my shield to knock down a few people, I realized that I was Captain America, so I must have a way to make it to the cliff side. I reached down at my belt area and grabbed a grappling hook gun (I don’t really know that much about Captain America, but that seemed a lot more like Batman than Captain America to me). I shot it into the ground that I wanted to land on, and somehow was able to slide down it and land on the ground instead of falling into the abyss. As I landed, I held onto my shield, but I still used it to knock down a couple more people. The next part is a bit fuzzy, but I believe there was a gate at the top of this mountain that I went through, and I was no longer in Captain America’s costume, but instead in the backyard of someone’s house.
I decided to search for Yev, but all I could find were cats. I eventually got to the front yard area and the road in front of the house, and just as I was about to give up, I saw a little kid. I went over and asked the kid something task related, maybe how do I get a costume, but I don’t remember what. The kid didn’t answer me, so I went back to searching for Yev. As I turned around, I saw another kid, but before I could talk to her, the original girl came over to talk/play with this girl. However, they were all of a sudden older, like teenagers or college age kids. I asked the girl I originally spoke to how she transformed like that, and she showed me this really simple dance that involved clapping your hands in front of you. I tried it myself, but it didn’t work for me. I then asked the second girl how can I summon Yev, and she told me to cook. So I went inside the house and passed someone that I know cooking using some weird wok/frying pan. I went to the kitchen and started desperately searching the cupboards for food. Finally, I found mustard, but nothing else. Then I saw cheese sitting on the counter, so I grabbed a slice of cheese and squeezed the mustard onto the cheese. I then took this to the wok/frying pan and held it over the steam coming from it. At this point I guess there was wax paper that I was using to hold the cheese, and somehow the mustard started to “melt.” Once that happened, I decided that I finished cooking something, so I went outside to use the food to find Yev. Sure enough, just as the girl had taught me, cooking had summoned Yev, as he was walking around down the street. I went over to him and greeted him, but he didn’t seem that excited. He looked exactly like he did last time, so he probably is still mad that I tried to electrocute him 
. He eventually got excited, though, and we started doing some kind of handshake/secret handshake greeting, where I was using only one hand to spin Yev around in the air. It was pretty cool. I was just starting to enlist Yev’s help in accomplishing tasks, but alas, I woke up at that point.
When I was doing the chemistry bonus task, my plan was to summon lightning from the sky and cause that to suit me up in Thor’s costume, but that didn’t work out. Now that I’ve been Captain America and the Hulk, it seems like I’m slowly becoming each one of the avengers. Maybe that will be my new personal goal for the next LC.
I was a little confused though because of my fake memory LDs were both loooong, so when I woke up and realized that the two long ones didn’t happen, and the short one did, I wasn’t happy. It was fun/vivid/aware though, so I can’t complain.
I am working a little on how to learn what my goals are in dreams better, but my main goal is lucidity. The more of it I have the better all of it seems to get. Like stability, memory, awareness, and vividness.
