Happens all the time to me too. Sometimes it's stuff that happens the next day, sometimes it's a month later. I remember having a dream where I was in a chat room talking to some friends and I typed something, correcting myself along the way ( click click backspace click click click click backspace backspawce, etc ).. and then about two weeks later it happened the EXACT same way... I typoed the EXACT same way, fixed it the EXACT same way, and the EXACT same things were already typed. I was like, "Woah, shit, deja vu." Was pretty weird.
