Fire in the mind/True form

I had this dream not long after falling asleep in the early hours of the morning.

From what I remember, I was at my mother's house in my old bedroom where I spent much of my childhood. It was empty save my old bunk bed and stacks of magazines I'd dumped there. For some reason, I was reading the magazines in the room. I also had a gun with me with the intent of shooting anybody who walked in on me.

The dream then changed and I was standing outside in the back garden of the same house. It was night time and al the lights were off in the house save the kitchen (which is accessed by going in through the back door), and my bedroom (which can also be seen from the outside from where I was).

My sister was there with me and so was my mother's gossipy neighbour (I mention her in another dream on here a couple of years back). The neighbour ran over and said she could smell burning, and kept pointing up at my bedroom window; she seemed convinced that someone was up there setting fire to the place. I panicked and decided to go in and investigate, taking my gun with me (I don't know what I had a gun, I just did). My sister followed after me, but didn't come up the stairs with me to my room. When I got there, I found the lights on, but nobody was there. There was also smoke, but no fire, and no discernible source. Even so, I was convinced someone was there, so I explored the other rooms (bathroom and the other two bedrooms), but found no-one. Also, the other rooms were in complete darkness.

The dream switched again and I was back downstairs talking to my mother, who was a different woman in this dream. This time, the downstairs part of the house had also changed and the lights were now on. I also had a step dad and step brother (both of whom were very fat), which I do not have IRL. My mum was telling me that last time she saw me, she didn't feel we connected anymore. I said I was sorry she felt that way and embraced her, saying that I'd try harder.

Then, an argument flared up between my step dad and I, and my mum joined in. I angrily retorted and told both of them that I was leaving and not coming back and that I never wanted to see either of them ever again. I walked out into the street (it was still dark outside) and started walking up the road. My step brother kept on taunting me, so I told him to "Piss off". My stepdad then started chasing me up the road, and for a fat guy, he could run.

Anyway, I ran from him until I got to the corner of the road, where I heard a voice say "It's time to show them your true form". I turned around to face my stepdad and said "I'm not the person you think I am" and then started to transform into a huge beast. I felt myself growing in size and strength and my stepdad and brother backed off and started shooting at me, but because of my size, the bullets had no effect. I used my strength and size to push them back, but I wasn't trying to kill them, I just wanted them to back off and leave me alone. That was it.

POSSIBLE MEANING: I've been having a lot of issue in my life with religion and religious people lately. You see, many years ago I used to be a Christian myself, but I deconverted, and this has become more apparent in the last few years, my apostasy strengthening the more I learn about how twisted and corrupt Christianity truly is. The more I learn, the less I want to do with it. However I am almost sandwiched by it. My mother and sister are believers, and so is my girlfriend of 2 years (who suddenly went hardcore this summer, as represented by this dream). I recently told my girlfriend, my sister found out through another person blabbing and the only person who does not know is my mother, and there's no way I could tell her.

I think this dream touches on the whole thing of me "coming out" to my mother (that is "showing my true form"). Me being chased around I think represents the Christians in my life who do know trying to draw me back into it. In the dream, I resist the people who tried to shoot me, but I didn't want to kill them, just get them to back off. Similarly, I do not wish to try to deconvert my girlfriend, sister or anyone; they have their own paths to walk, and if they leave the faith, they should do so because of themselves and not because of me. This I think is represented by me trying not to kill the people shooting at me.
