Would it be possible for something that you did in a Lucid dream to still be there when you got back? Has anyone found themselves in the exact spot they were when they woke up from their last lucid dream?

I suppose it would be possible to like... write your name on a wall in your dream and see it later... but thats just because you willed it to exist again.

Wouldn't it be fun to have a in-dream dream journal? XD
