I am unconscious

What is the most resilient parasite? Bacteria? A virus? An intestinal worm? An idea. Resilient... highly contagious. Once an idea has taken hold of the brain it's almost impossible to eradicate. An idea that is fully formed - fully understood - that sticks; right in there somewhere. 

- Inception

A thinker is vulnerable to ideas, I am a thinker,
Plant an idea in my mind,
And it will stay forever,
Conscious, subconscious, superconscious,
I am unconscious.
