Staying conscious in theta/delta deep sleep in order to reach the state for OOBE

[Snow Pellets]

I was wondering if it is possible to retain consciousness at the very beginning of the night when you enter deep theta/delta sleep before bouncing back up for your first REM period. 

I have done it early in the morning right after a brief awakening (which is common according to all the information that I have read out there about the subject).. but I'm wondering specifically if it can be done at the beginning of the night.

If I just focus on my breathing (not easy as the mind has a tendancy to wander in order to fall asleep), should that alone be enough to take my conscious awareness through theta/delta sleep, through the hypnagogic state, and finally onto what Robert Monroe called "Condition D".. full sleep paralysis and loss of physical sensory perception, where the vibrational state can be brought about for a fully conscious OOBE exit.

Generally, no.
The reason is because you're already exhausted after a long day... AND your body knows that the night time is when you "sleep".
You've programmed your circadian rhythm to put you to sleep around that time.

You find it works better in the morning because you're now well rested.  Mind and body.

But it could be possible.. in Monroe's book "Journeys out of the body" there seems to be plenty of instances where he is able to remain awake during deep delta sleep and have an OOBE right afterwards.

Yes, it is possible. Just harder to achieve then after a nights sleep
