hahah yeah, it seems like while your dreaming your actual waking mind has little input on whats happening and if an idea is presented (like your teleportation device) then your subconcious mind will come up for a reason for it to be there and you will accept the idea and push it off. Thats the thing with lucid dreaming, if you question everything, then you will pick up on things like this, and have more control over your dreams.
