That report was actually declassified years back. I've read it several times. I am actually very familiar with the Monroe Institute. This is not something hidden. But it has never been given mainstream attention. If people knew that they could separate from their physical body while sleeping and consciously travel, then they would realize there is no death and that we truly are Eternal Spiritual Beings. That would change the global consciousness in an instant. The good news....more and more people are awakening to this. What an exciting time to be alive!
