Interview with Sandie Gustus begins around 1h17s
"One particularly interesting category of consciousness is called intermissiology, which examines the period in-between lives, or the intermission between lives, she continued. This relates to OBEs, which offer a unique research tool to examine consciousness outside of the body, Gustus noted. Dreams are connected to the physical brain and typically lack a beginning and an end, while OBEs offer more control, clarity, and understanding, she said. The problem with OBEs is not that it's hard to return to the body, but that one is too quickly jolted back to the body, because of environmental and other factors, Gustus added."
