Okay, it seems like all of my dreams recently somehow involve a house that (in the dream) I think is mine. But they’re always radically different, and many times my dreams will involve running back home or trying to find my ‘real’ house. The other night a DC was trying to help me find my ‘real’ house, and I got sort of telepathic images of what it looked like. But it wasn’t my own home anyways, it was more like a cave lit by candle light. Sometimes I WILL be in my actual house but it will be demented in some way, like a doughnut shop will be attached to it or there will something REALLY strange about it. It has never seemed very important to any of my dreams and I never gave it any thought until now, but looking at my DJ almost every single one of my dreams involves something like this.
Well, perhaps we don’t like dream analysis, but giving dream interpretations can never hurt 
I can only give you my opinion, as to how I would interprete such a dream in case I dreamed it. My dream language may be nonsense to you, or it may not, but that’s the only thing I can say about it.
So in case I dreamed this dream, I’d say this dream house represents my own body or my psyche, because that’s what my dream houses often represent and especially because I have a feeling the house is mine. However, I feel it’s more about my psyche here than my body, so I’ll consider it like that.
The different houses might symbolize some changes are happening in my psyche. Perhaps irl I’m now in a period where so much ideas enter my mind that I’m totally lost… I don’t know what to think of them all and I keep searching for those ideas which satisfy me enough because they somehow intuitively give me a greater self understanding perhaps? Am I looking for my own identity, but I can’t seem to find the right way? This could be the case because in the dream I’m trying to run back home, but I keep searching for my real house, my real identity, my real self.
Ahh I’m getting some help! This DC… could it be a person I’ve met or spoken to irl who gave me some valuable insights as to where to find my real identity?
A cave lit by candle light… Perhaps the DC wanted to point out that you don’t need a true house as we know it to find your own self? The world is like shadows depicted on the wall of a cave, Plato once said. Perhaps this DC is pointing out your true home lies not in the daily world of shadows and illusions, but beyond that veil of outer objects. Could this be an invitation of some kind? The fact that I don’t feel this is my true home might symbolize I’m not ready for that step, or that it’s just not my way of finding my true home, my true identity.
I’m in my real house but it’s demented… So whenever I’ve found what I think is my true identity, it’s not really what it should be… A sign that this isn’t really IT? Perhaps I need to look further? What would happen if I accepted the cave as my home? Would there also be some really strange things about it? Perhaps it would be not a bad idea to try it out
Hope this makes some sense within your dream language
Try to use this “house” element to your advantage, tell yourself (MILD) next time you are in such a dream that you will be lucid 
Wow, that sounds like a VERY likely possibility. Except for one thing you got completely wrong but probably because I didn’t explain it too much. The DC was my cousin, who’s 10 years older than me and I’ve hardly talked to at all since I was 8. I don’t know what he could mean or symbolize, because I don’t really know what he meant to me then and he doesn’t really mean much to me at all now.
Yes hard to tell what your cousin could mean here… The fact that he now appears in your dreams could be a sign for some (subconscious) need to visit him. Perhaps visiting him might give you a clue as to why he gave you such a telepathic message in your dream. If someone who you haven’t met in a long time suddenly appears in your dreams, then I don’t think this is just random brain signals, but an important signal that you somehow will regain contact with that person, a contact which is necessary to understand the deeper layers of the dream. At least imo
Maybe, I don’t know…
I will be seeing him at Christmas, but he usually doesn’t stay very long.
I tried visiting that cave again last night, and I did find a cave but it was a lot smaller. Also, in the dream I was an alien hiding out in the cave from the military. (It ended with me getting slaughtered with who knows what kind of secret weapons. Surprisingly I wouldn’t call it a nightmare because I wasn’t very afraid. The next dream I had that night was the exact same situation except I handled it better and survived.)
