What does it mean if you have a dream about Jesus?

I'm, Greek Orthodox and I had a dream about Jesus and Mary. "I was sitting and my live grandparents dinner table where a huge news flash came up on the T.V behind us. It said that the world was going to end by an alien invasion, because there were bombs in the sky and soon enough the aliens would release them to blow the world up. Nobody believed this except for my grandmother who went to Church and prayed that this wouldn't happen. On the day the scientists predicted that the worl would end I was at my school athletics day. Where I went over to the long jump and saw this lady dressed in black (My grandma in real life described this lady as Mary) where she said 'you are the chosen one, run up to that fence' she gestured me to the fence, I ran there and I went through the clouds where Jesus was sitting on a big chair and said the world will end and you must continue the race. So i dissapeared onto a boat where a saw another boy my age or older he said 'what are you doing here? Are you chosen too" I told him that I met Jesus and he told me that I was chosen. On this boat there was a huge thunderstorm, we looked back and saw a tropical island with the palm trees swaying and big waves, then a huge U.F.O appeared and aliens came from down from the U.F.O and where searching fro anyone alive. He said 'The only way to survive is to swim to the island' so we swam together and were in a cave where from there I had heaps of visions of us having kids, continuing our race and defending ourselves from the aliens." My dream was long but I just wanted to know if this had any relevance for anything... The dream felt really real and when I woke up and started hyperventilating. I know it sounds weird with the aliens but anything is possible, I would really like to know what people think of the dream.
