I have the same thing, I can "walk" through my childhood home. I see how the living room was set up, I can walk from there to my bedroom and "see" everything. Honestly if I had good art skills I feel like I could draw it out pretty well. However I would in no way describe it as looking like I'm there at the real thing or looking at photograph, not even close really. It's kinda just a hazy construct in my mind.

I feel like that is where a lot of the miscommunication comes from, people who think others can close there eyes and be transported somewhere else by imagining it. That is unless I actually just have aphantasia.
