If this dream has been coming back for a decade, the real question isn't so much what it means symbolically, but why your brain decided it was important enough to loop it back to you constantly. Recurring nightmares usually settle in because there's some unresolved tension that stays active somewhere - not necessarily traumatic, just something that never found its resolution. It could be tied to your relationship with that place (your childhood home), to a period in your life, or just to an anxiety pattern that crystallized at that moment.
What people generally don't mention is the effect of "constant reinforcement." You say you talk about it with everyone - and I'm not trying to call you out on it - but the more you tell the dream, the more you reinforce it in your memory. It's a cycle. One thing that actually helps a lot of people is writing the dream down once, just once, then really trying not to talk about it for a few weeks. Just write it, don't ruminate. It lets your brain breathe a bit.
Another angle that could be useful: before you go to sleep, imagine the end of the dream differently. Not in some fake positive way, but simply - you find an exit, you call someone, you use a door that wasn't there before. It's wild how much that can break the pattern. If it's really affecting you day-to-day or it's become a real obsession (which is kind of what you're describing), seeing a therapist wouldn't be a bad idea, especially one who knows their stuff about recurring nightmares specifically.
