I tried using this, and got to the bottom of Delta (30 min in) while still completely awake and completely still. Woo, let me tell you... Wild ride. Starting about 10 min in (probably around REM) it kinda felt like I was getting high. I have slight vision problems in the dark, anyway, but with this I was seeing subtle waves of color, some of them shaking. I had a wide smile for no good reason for maybe 3-4 minutes as I drifted awake through what was supposed to be REM. I got itchy in a couple spots, but I felt like not moving instead of scratching. Also... the visuals. I was half dreaming at some point, seeing a very realistic rocket ship, but that transitioned back in to color waves as I realized I was still awake. When I hit, say, the 28 minute mark (the low point on the graph) I got a wildly strong chill from head to toe that made me decide to stop. 
TL,DR: Expected sleep. Got high. Not disappointed.
hehe, cool :)
My first binaural beat experience was similarly trippy. Only tripped the one time though...
