Every now and then I wonder about some questionable post here and there, but in general what people experience and relate resonates with my own experiences...what they describe is similar to what I experience, so most on this forum are very credible. But as you raise the point...how can you prove what only you experience and others cannot share in? That is the main frustration I have with lucid dreaming... I cannot REALLY share it. So I seek out kindred hearts here on the forums. To a true skeptic, all you can say is that it is unreasonable that there is this conspiracy involving thousands of liars worldwide...the scientific evidence notwithstanding.
