What will happen, exactly?

Ok guys, so ive read a lot about December 21 2012.

Suppose its all true, then what will happen when we wake up on December 22?

What do we experience physically? Mentally? Dna changes? full brain capacity?

In other words, what will be different that day from all the 2012 years before?

How do you know you'll wake up?
Seriously, I don't think any great event will happen.

I think we shouldn't have expectations. Expectations cause disappointments.

I like thinking that in reality no one knows and that it will be what we make it to be.

But if you want a more accurate answer, from all I read the possibility of which I most sympathized was that there will be a "massive mystic experience" happening all around the world. Everybody will be in touch with the divine for a moment, reminding us of what we really are.
