Has this happened to ou in the past? If so, you may have Narcolepsy, which is the tendancy to lose conciousness for brief periods of time at seemingly random times, usually triggered by something such as extreme emotion. That may also explain that dream you had in class, since people with said disorder go into REM (Dream time) sleep much sooner than normal.
