There have been times when I basically did things as you. Almost like the part on battlestar gallactica with baltar on the base star. (He was in a hallway, talking to a cylon, and viewed it as a forest or some such.) Usually it is just something else though. Outside of the statements triggering a nostalgic, enjoyable, or relevant memory, I don't have it exactly as you do. ALSO, the two can seem very real, but I know they aren't, if you know what I mean.
