What exactly is "normal" and why?

[9_ki_kid]

We base what is normal off of all of our memories, but nobody holds every memory that ever was, so everyone has a different perception of normal, but if there is or isn't a universal normal, depends on the expanse of the universe.
If the universe is unlimited then there is no universal perception of normal.

There can be no normal that applies entirely to one thing while not applying to another thing, because everything is relative to everything else (some of everything effects everything.),
but something can still have less or more of something. There are things that seem to be entirely one thing, like colors. If you see something and think it's entirely white, that's only because your mind can't comprehend anything brighter, so it only sees white as a replacement.

Is there a normal to us? Well it depends on the limits of our imagination, and perception. It seems that we do have a limit, but I think that is only because part of our mind is subconscious and part is conscious. I think that the stronger our connection with our subconscious is, the less limited our perception and imagination become.
