crazy dream

i was in my backyard with a crowd of people. it was nighttime. then all of a sudden two triangular shaped objects came down from the sky and joined together and were hovering over everyone. an old lady from the crowd grabbed on to them and then they started ascending back up into the sky. everyone started panicking. then there were flashes of lightning and in my dream i knew that it was the end of the world. then a gigantic robot appeared from a distance and started walking towards us and we all started screaming and running away. then i stopped and turned around and there were two people with the old lady and they were walking her up the stairs of my deck. the robot was on my deck. he said something like dont be afraid for the future. then i woke up and i was terrified.
