If you do actually suffer from sleep paralysis, might I recommend the soothing sounds of Dredg's "El Cielo", an entire album based on said topic, not to mention wicked awesome independent of any theme in particular. Seriously, I heard it for the first time this fall, and I can't remember a day where I haven't listened to at least one song from that album. Not to mention should you go to dredg.com, you can download the media player and listen to the whole album and watch their one video, which is ultra sweet, all for free. No, I'm not a member of the band, so this isn't a shameless plug, this is simply a plug for a band I happen to like.
