A riddle I found here: http://www.expandyourmind.com/logicprob ... eral.shtml
WHAT AM I?:
If you look, you can't see me.
If you see me, you cannot see anything else.
I can make you walk if you can't.
Sometimes I speak the truth.
And sometimes I lie.
What am I?
I'm gonna put the answer down here:
Answer: A dream
