I am trying an iPhone app Smart Alarm,which works by Laing my iPhone on my pillow and it detects vibrations and deduces from that my sleep cycle stages! In my sleep I dreamed that for this app to be effective I needed to give it a name. And not like Smart Alarm, but my own pet name, a nickname. A name to give it power, A name to give me power over it. I wonder whether it's the old magic concept: if you know someone's name, you can use that to overpower them.
