The biggest shock for some people will be when they wake up on 31st Jan and realise that nothing has changed. It's absurd, but a lot of people genuinely believe that the 'Brexit date' is a sharp cut-off where Brexit suddenly magically happens, everything is instantly different, and all 'foreigners' leave. I was walking through a market the other day, and I actually heard a woman ask her friend 'Will they be laying on coaches to take them all back home?' There isn't a lot of understanding that a long and tortuous negotiation process lies ahead.

Regardless of whether you are Leave or Remain inclined, the level of ignorance out there is astonishing.
