Rewind/ play frames backwards?

i have 4 main sections of my site and i would like it if the user is deep into section 2 and wants to click a button to go to section 3, section 2 actually reverses every tween/action it has ( breaking down ) then goes to section 3. i would prefer this rather than an abrupt shutdown section 2 and section 3 starts.

how is that possible?

example of what i am talking about :

thanks.
