I've been having some trouble with my WILD attempts for quite some time. While sitting, I haven't had much luck at all, but while laying down I have been a little more successful. The only problem is that I just fall asleep. Is there anything I can do to hold onto my awareness?

I recognize a pattern of events that happen while I fall asleep, but it seems that at the very last moment, I always loose consciousness.

I've had many lucid dreams, but mostly in DILD
form. I keep a journal and I usually add three non-lucid dreams a day with an occasional lucid maybe once a week.

This is my usual night:
I go to bed around 3AM(I get off at 1AM), get on youtube, listen to music, and relax. Around 3AM, I feel tired and can hear a soft ringing in my ears. I get into bed, lay on my back and get comfortable. My breathing slows, I feel blissful and my eyes seal shut. I feel my head expand and I feel a (comfortable)pressure in my brain center. My thoughts may run off on their own while I don't pay attention to them. I can almost hear thoughts as if my thoughts are thinking themselves. I see very dark waves of light. The ringing gets louder and spikes in volume every 30 seconds or so lasting a few seconds. When the ringing is at it's loudest, I can actually hear voices, music, or ect. It usually has to do with whatever I was watching or listening to before I went to bed. I start to barely see very dark moving visuals that flash by quickly. Each one last three seconds or so, but they are very dark as if someone were to look into their reflection via a dark-tinted window. At this point I always fall asleep!

For two years now I've attempted to WILD sitting up, but just can't fall deep enough. I meditate twice a day for at least an hour each which is pleasant, but no dreams. While sitting, I get as far as moving imagery flashes, falling sensation, and then nothing.

Any tips on riding the wave without falling asleep?
