Many people who can remember their dreams often look forward to what their subconscious mind wishes to show them.
Calvin, Reggie, and Jason are not among those people. Their workload at Sentry Ridge, and their efforts to get their band ready for their upcoming battle of the bands contest, are taxing enough. But each of them have personal issues that they wish would disappear, but instead follow them into the dreamworld. Others might find their dreams amusing, maybe even hysterical. Unfortunately for these three, the meanings behind their dreams distress them even more.
Billy and Sam aren’t experiencing dreams because they’re not getting enough proper sleep to allow them to dream. Because of that, they’re both experiencing lack of REM sleep waking hallucinations. Sam’s subconscious, it seems, is playing practical jokes on him. Billy’s subconscious, however, is attempting to convey a serious message, and apparently doesn’t care how dangerous the delivery gets.
