Have you been reading romantic novels lately by chance? This is what usually happens to those who do. It could mean many things here starting with your Prince Charming may show soon and sweep you off your feet. TV and Novels have a way of playing with our imaginations nowadays but dreams do come true if you believe hard enough. Some unrealistically ones die hard so I would say believe in the first one and good luck
Absolutely nothing. It's just a dream.
Just a dream or maybe one day you'll meet this guy.
