I am wondering if getting free from illusion is an illusion in itself. Illusions within illusions. That said, I am not sure we ever wake up from our dreams/nightmares... or even that it is desirable. What you are talking about is consciousness which despite our best efforts remains a mystery shrouded within a mystery...
It can be called the monkey mind. It certainly makes a lot of distracting noise. Illusions are always mysterious till seen through, I think. I concentrate on breathing in and breathing out. It is enough purpose for me. And yes, waking up is difficult: most of us never get there.
