Physicist Tom Campbell and researcher Bob Monroe discuss their early experiences with out-of-body experiences and their collaboration in researching expanded states of consciousness. They engineered the first binaural beat tape to facilitate out-of-body experiences and explored various methods to induce altered states of consciousness. They also delve into the setup of Bob's lab at Whistlefield and the use of galvanic skin response (GSR) measurements. The speakers touch upon the establishment of the Monroe Institute and upcoming discussions on remote viewing training and the concept of reality.
