Scary, weird dream

Hi, I need help understanding why I'm having these weird dreams! Last night I had a long dream where it started by me recently moving into a new house or apartment, I cant remember which one it was. I think someone tried to break in the night before but I wasn't there so when I arrived the next day I called everyone in my family to come over.

When my family got there we were all together outside and all of a sudden some type of war began where big clear plastic balls filled with glass were falling from the sky which exploded and made everyone blind except me because I quickly covered my face and then other balls filled with some type of gas fell from the sky too (I'm not sure who it was throwing the balls but it felt like it was the government). I was the only one able to see and move so I had to help all of those around me. It seemed like it was happening everywhere because I remember a lot of people screaming and covering their faces. Then it turned black and when I opened my eyes me and my family were in a dark room that felt like it was a torturing place or something close to hell. We were being kept inside locked with no food, water, or any type of resources. There were tvs in the room that were showing videos of people outside living a glamorous lifestyle with food, money, etc. We had to make a choice and sort of "sell our souls" to be released and join them, if not we were gonna be kept inside. The dream got even weirder after that I can't even remember. Then it jumped to the same black room but this one was more creepy, kind of like a war zone. I was there with others, but these people were strangers. There was a tall bald man who gave us instructions, telling us how we were going to receive our freedom again . We had to fight for it. The rest of the dream consisted of me and the others fighting off demon like creatures. There were three levels of fighting. In the first we had to fight objects. They were floating objects like couch pillows we had to slice (weird right?) and then the last of the first level were like small crawling ants that were biting us so we had to kill them. We were given weapons ( I was given a swiss army knife). We won and passed to the second level. The second level was us fighting demons dressed as halloween like creatures including a grim reaper. In this level I had a long sword. It seemed like I was the strongest and smartest of everyone because I kept fighting the most and winning. We won again. In the last level the ceiling was falling down slowly and we had to sort of cut parts of it before it touched the floor. It seemed like some kind of video game. There were three of us and we were given some sort of knife to scrape off the ceiling. The others were slow while I was quick doing most of the work. I was going fast close to winning and I remember asking the others why it was so hard for them. They said they were blinded by the light and couldn't see exactly where to scrape. I noticed the big ball of light they were talking about but it had no effect on me. I started grabbing pieces of the ceiling, instead of scraping it, kind of cheating but not really because I remembered the instructions and they never said we had to only use our weapons. We won, but then the bald man said that we weren't done yet, basically he had lied to us about being freed. However, all of a sudden we were lifted from the floor up into a movie theatre, wtf? We were in the lobby and I turned right where I saw a line for a movie that was about everything we had gone through, like a horror movie. Which scare the hell out of me btw. However in the dream I was sort of fearless. The people in the line looked lost, like they were sick or something. I walked outside and everything seemed so normal and peaceful. I felt strong, sort of invincible, like I could do anything. Then the dream ended with me saying "I need to go find my mom". LOL.

It was a weird dream but the feeling I had at the end of it was great I wish I could feel like that in real life and I kind of did feel that way as I was waking up. What does this dream mean? I've also been having dreams of sex, touching myself, etc. It bothers me because it makes me wonder if I'm mentally ok or something, I mean who dreams of this shit? (Excuse my language). I'm a very nice and clean person, I don't know why I'm dreaming this stuff. Btw I'm a female in my early twenties if that helps. I would really appreciate some help because I'm HIGHLY confused. Thank you!
