What does it mean if a person has an inner experience in the presence of a teacher but cannot replicate it later?

According to Osho, if an inner ‘experience’ near a teacher can’t be repeated, either it was imagination boosted by the teacher’s presence, or it was a real but brief leap. The touchstone: did it change you? If nothing in your personality shifted, it was fantasy; if you’re subtly different—clearer, less afraid, more trusting—it was authentic. Don’t mistake imagination for realization; verify through transformation.
