How to 'predict the future' All you have to do is write a status on your wall as usual. But before posting, select the clock icon and set the date - which can be any time in the past (or you can schedule it for the future.) Here we've picked a random selection of dates and times, but you can make it as spooky as you want. And voila. Once you hit publish, it will appear in your timeline at the date you set, and you can trick all your friends into thinking you're psychic. SOURCE:MIRROR.CO.UK
