At the end of the video, you will notice a cluster of balls in the air, hovering in front of the person. The person stares at the ball and immediatly sheds his physical body and realizes his etheric nature.
I think the cluster of balls is the DMT molecule, commonly called the "spirit molecule". Alex Grey has done a picture of this etheogen and he also helped create the end of that video.
Except that DMT looks like this, and the "molecule" in the video doesn't, even accounting for the space-conserving vs. ball-and-stick model. Unless I'm misremembering, which is quite possible, considering how long it's been since I watched the video.
