n.
Something, such as a fantastic plan or desire, that causes an erroneous belief or perception.
My entire life is an illusion. No; truly. At times, I can't tell if I'm in a waking dream or a torrential downpour of nightmares. I'm not sure what's real and what's not, because reality fades away into a general grey fog, a misty spiral of nothingness that holds complacent numbness, all for me. It's hard to wake up and not know if I've truly woken up, or if I'm still asleep.
