Sudden awaking/realization

I have seen some videos in Youtube (here and here ) where it seems that just by standing in front of Papaji, people start laughing without control. Somehow it is implicitly said that this reaction is related to an awakening/realization experience. My questions are: - Is this true ? - How is it that just the presence of a teacher is enough for such an experience ? - Can we say that this experiences are real Enlightenment ? Answers with references are strongly appreciated.
