An interesting thing that I found is that deepening techniques work in reality. In other words, they help me stay more awake.
When I get tired I'll rub my hands, peer at objects, and when nobody is around I'll even spin in a few circles.
These techniques work better than anything else I've found at staying awake (particularly spinning).
I tried this because I figured deepening was really just a way to make your mind more awake in REM sleep.
This has been a very good application in my waking life.
I don't think I'll try diving into the floor in real life yet.
