I’m pretty sure that Dream Recorder wins the award for Creepiest Mac Application. Then again, it’s also one of the most interesting and innovative that I’ve seen.
Dream Recorder films you during the night using your web cam’s night vision mode (iSight comes built-in on the new MacBooks) and then analyzes your movements to determine your sleep cycles. It determines (with suspect accuracy, I suppose) how long you were in deep sleep and even how long you were dreaming. Dream Recorder can be set up to play certain sounds during your sleep cycle (rain, birds chirping, etc.) to influence your dreams and it can even set an alarm to wake you up at the ideal moment in your sleep cycle.
Perhaps most interestingly, Dream Recorder has a built-in sound detector that begins recording audio any time it detects you snoring or talking in your sleep. For me, it only picked up sirens outside my window but you can manually change the sensitivity of the detector.
Dream Recorder is free to try (you need Mac OS X version 10.4.9 or later) but after your two week demo, the program costs $45.
OK, I know that I toss and turn a lot in my sleep but this is ridiculous.
