One of the weirder things I genuinely believed in was a physical border between the world of the imagination and the world of the 'real'. This border was a sharp division (like the equator or something) which sat on the very outmost edge of the universe and represented a border which mankind could never cross.
I used to believe if you could build a spaceship with a warp drive, a person could jump to the border between the two realities and put their hand through the curtain, to the other side. Everything that existed in 'unreality' lay on the other side... with effort you could bring people and objects back through the curtain - (they were unable to cross through on their own free will)- things like the animated Transformers on TV, or the imaginary heroes from books that only existed in your mind.
Later on this would evolve into my working definition of the afterlife for many years.
