I never really got a clear answer on this, and I have looked and asked around nearly everywhere. All crap aside such as, depends on how experienced you are, what tech you use, how many times you 'spin', REM periods... Give me some insight on how long you are actually experiencing the lucid dream. Real time, and how long it seems.

Keep in mind I am kind of a beginner at attaining lucidity. I have done so, but I have difficulty remaining within.
