Do you ever have a dream and then a few days later it happens? wtf is that?? o.0?

okay, for examples, i had a dream that i was talking to a hobo and mr. hobo sneezed. and a few days later, i saw a hobo on the street so i went to give him some money and he sneezed. this mr. hobo was the same mr. hobo from my dream cuz dream mr. hobo and real life mr. hobo looked exactly the same. so, wtf is that? o.0
