It snowed...or was it a figment of my imagination?

We got 12 weather e-warn messages during the night. They all stated that we were in line for a major snow event and were under a "heavy snow warning". I woke up at 6:04am and found that it was snowing. There was white stuff all over the ground and it covered the roof of the house. I took pictures because it really wasn't that cold outside and I wondered how long it would last. I went back to bed and fell asleep. At 11:26am, I went back outside with the dog. I took more pictures because there was very little trace of the snow left. I began to wonder whether it was a figment of my imagination. 5 1/2 hours earlier, there was snow everywhere. Currently, you can't tell it even snowed or that there was precipitation at all. Did I make it all up, was it all a dream? Or...is it the crazy Alabama weather at it again?
