I'm deceptive, but right on cue; the silent tell on what you do. Paving the path inside your head, changing it up when you're in bed. It's always you, as far as you know, and I've been your mate through the whole worldly show. Like a stick that's dropped from a tree, I'm a part of the whole that has fallen from thee. Jewels of wisdom collected insight, your thoughts on this riddle are the answer that's right.
What am I? Stop by Wednesday for the answer!
I gave you a clue!
