Vanishing suddenly

Last night, I had my second lucid dream. In it, I became aware my mother, who I had just been talking to, had vanished. This sparked lucidity, and I euphorically ran down a track at a college I live nearby to, shouting in triumph. I nearly lost lucidity, so I calmed down. I have never flown in a dream, so I tried. Nothing happened, even though I knew it was a dream, I knew I was able to fly if I had the expectation present. Disappointed, I saw my sister walking ahead of me, but she was walking funny.. like she was made of melted putty, swinging her arms and legs strangely. She transformed then into a large, sinister character with a monstrous face torn in some parts to reveal his skull, which was slightly on fire, wearing a trench coat. <PERSON> meets <PERSON>, then takes nightmare steroids and grows. He strode quickly toward me, then transformed into an obscure acquaintance. My desire in dreams is to talk to DCs, so I asked him, what do you represent? He answered, you, now. He walked away, gaining a blue toga and a massive bow, like a Greek hero, or <PERSON>. I looked into the sky, which started to fade to black, then back down to retain my dream awareness. I tried spinning to a new environment to no avail. Knowing this was a lucid dream, I started looking for some lucid booty, and I am not a pirate. I asked several women I saw to undress, but they vehemently defended their honor as any woman in a street would, making me feel self-conscious and slightly abashed. I walked into a nearby building and could not change anything. Nothing, I was in a very low degree control over the dream. I talked with a couple people about making plans to go to another dream, and they were drawing up plans for it (a cruise in a wondrous tropical sea with a boatload of girls), when I walked past a man I knew sitting on a couch. He said, <PERSON>, this will always be a part of you, then proceeded to molest a girl I know who he was next to, who was sniffling and unresponsive. Enraged, I lost sight of creating a tropical paradise and wanted to hit him, though I am not generally violent. As I moved slightly toward him, I merged with the girl on the couch, who turned into a very close lady friend, and the dream turned sexual. I woke up feeling angry, ashamed at the disturbing content and thrown off in general. Did I expect to be turned down? Was the amorous ending a reward for trying to attack evil, or did I give into my anger and become the evil itself? Mainly, I see the strangeness of it all as being caused by my inability to control and manipulate my dream environment (not able to fly, create new dream, etc.). If I had been flying, I think I could have escaped the nightmarish elements of it. The real unanswerable question is, why are the two evil characters in the piece, the fearsome monster hero and the predator, a part of me, and how can I either integrate them into my psyche... or destroy them? Love your enemies despite their wickedness, even if they are within, or are these weeds in me that I should be rooted out and burned?
