A binary tree dream

I slept OK last night. I now find it is still dark at 6:00 in the morning, so no more blazing sun to wake me in the morning. I had a dream where an android device was trying to make it immortal, by some software update. Later the dream changed to a scientist trying to destroy the world. Somehow there was a missing piece of his device. Other people worked out part of the puzzle and starting designing the rest of the machine. The blueprints were lost, but found by other people. As the device is built that part of the "multiverse" is destroyed, but another tendril shoots off.
