At a previous job, I had a co-worker that had some issues with insomnia. This guy is an incredibly gifted engineer and musician. He spent many a sleepless night thinking about what would stimulate his brain to create the correct harmonics to trigger a sound sleep. The end product of his research was a coil that encircled the bed that was supposed to trigger certain sleep states through the manipulation of magnetic fields and such. We didn't know what to think about it, but were very happy when he started sleeping soundly.
Recently I came across this article in the New Scientist in regards to brain activity during sleep and irregular dreams due to geomagnetic field spikes. Maybe Steve's reverse guitar pickup brain wave dream inducer was way ahead of it's time!
