Gesturing and deja vu.

: I have often noticed that when I point out something on someone else's face by pointing at my own, it is only on rare occasions that a person will choose the correct side of their face. A large majority of the time, the other person will pick the mirror-image of where I was pointing (for example, I point to the right side of my face, they pick the left side of theirs). I don't really know how important it is, but I just wonder what makes some people pick the "correct" side while others choose the other. Then again, for the people who do pick the mirror-image side, I bet they would probably think that I was the one that was wrong.

: Speaking of dreams, it is my belief that bouts of deja vu are closely related to dreams. My theory is that when we sleep, we go through thousands of vignettes. You can think of it as your brain running through a whole bunch of scenarios so that you'll know what to do should you ever be in that situation. We only remember these when we wake up in the middle of one, resulting in what we call a dream. As we go about our daily lives and happen to come upon a scenario that is similar enough to one experienced in one of these scenarios, it is this familiarity that causes what we sense as deja vu. That, in a nutshell, is what I think dreams are all about.
