Do Dreams Really Come True?

I had a great dream the other night that I thought I would share with all (especially mom and dad) and ask you the question, Do dreams really come true? In my dream my parents were planning a trip to Denver for the weekend (not that odd considering they were actually in Denver at the time) so they said I could call their cell phones if I needed them or otherwise they would talk to me early in the week. I went on with my day as usual and later that night there was a knock at the door. Guess who it was? Mom and Dad!! They had surprised me and were going to stay with us for the week! So tell me, do dreams really come true?
