After having a Dream Within a Dream several times (all of which involve you hitting your alarm clock), you finally awake an hit your alarm clock. It's only 8:10. Forget it, you say, it's time to just sleep through the alarm clock and blow off everything. You're self-employed anyway. In your dream, you hear the alarm in the background but tune it out, dreaming for hours and hours of some legendary mystical forest which you search for the Seven Triangles of Time. After finding the last one, you hear the faint buzz of your alarm clock, which must have been persistent because that happened ten hours ago. You wake up. It's 8:20. This is where time passes at a vastly different rate in dreams, give experiences of hours, days, months, or even years, in only a fraction of the time. The inverse is also an example, but one wonders why you'd waste your time like that. Related to Narnia Time.
- Dark City: Murdock has a dream implant that helps the main character master Tuning, running several lifetimes to teach the skill. It was supposed to be a quick dream implant that was supposed to make him simply lose his memories of Tuning, because he was a threat to the aliens who made the city. Even though it is short compared to its actual length, it runs much longer than a simple dream should.
