How can you bypass Theta and Delta?

This is an add-on for winamp I made. If you let it flash on your computer monitor while you sleep, you can choose any freqency (theta, delta, etc) for your brain.

Hello Graupel...

There is. Practice. Delta IS OBE. During the OBE the brain is in the Delta state- or at the least producing mostly delta waves. The body is asleep while we are projected, so it is not the states that causes loss of awareness, it is habit. []

Take care...

What is the true cause for us loosing awareness and "falling asleep" unconsciously?  Is it because the mind starts to drift when we aren't trying to remain awake and thus accesses  pre-programmed subconscious thoughts and makes the conscious mind dormant?

At the very beginning of the night when you enter sleep cycles consisting of non-rem sleep (theta, delta) I think that is what causes you to loose consciousness.. is there any way to bypass these sleep cycles?

If not, is it possible to somehow remain awake during these deep levels of sleep?
