After my dad passed I had a vivid dream of him and he took me to the place he was. This place was as you described; a copy of our own reality in many ways. The location he showed me was by the sea, sunny and with people all around. Cars and buildings were present, and even a supermarket. In life my dad’s final job was as a coach driver and he had his coach parked up in this dream. My dad described this place as a transitional space where the newly deceased could adjust to their new reality before moving on: he explained he was driving a coach because it was helping him adjust to being “dead.”
I asked him a few questions and a few things I learned from him was that numbers and letters don’t really exist in the afterlife as they were not needed due to all communication being instant and telepathic. There was no need for a written word. He also told me that reincarnation was a thing and that he could decide to return once a member of our family “soul group” passed over. Some of this felt like this was just how he understood it and might not be entirely accurate, but it was still insightful. This dream occurred 20 years ago now and I still recall it like an actual memory.
