My Robotic imagination

I start off Lucid in this dream ad I'm outside. It is night time and I was thinking about what would happen if something in a dream gets covered from your view and you look at it again. Would it be still there or would it change or disappear? I was walking around in a strange place somewhere in a yard with pine trees. I look over towards some huge houses and I see a trash dumpster sitting on the side of the building. It was overfilled and had bags on top of and around it. I looked away from it the back at it. It was still there. Looked away and and back at it, still there. Looked away a third time then back at it, this time it was an over hang that was part of the building. I laughed at that and went on to Find the Heavy Arms Gundam.
