After reading some posts I thought of an idea. Would it be possible to find things in dream environments and store them to see later? For example, you are walking through a forest and you see a strange plant. You could take it to your base or whatever and it would be there next lucid. I've heard of people having houses that they go back to but I'm not sure about this. Maybe someone could keep labeled doors from past dream environments, then open them like the TARDIS. Anyway tell me what you think.
