My first ever lucid dream involved a very strange and simple experience in a room that reminds me of the Matrix Loading Construct, only with a single desk, and a floating wall of mirrors. It was only a minute or so long, and contained a folder on the desk that I couldn't open before I slipped awake...

I want to return to that room to see what is in the folder. My question to everyone is this: If I can somehow return there, would it be like returning to a location in real life (nothing has changed) or would it be another recreation from a memory? I ask because I'm really curious about the contents of the folder. And if I can only return to it by recreating the memory, then the contents could change and it would be pointless. But if the room is a solid state that I created, then the folder will always contain the same contents that it did the first time I was there. I know this might be an opinion-based-answer type of question, but I still want to hear what everyone thinks.

Thanks!
