A childhood belief about father christmas

One Christmas Eve when I was about 7, my mom snuck into my bedroom and gently woke me up to tell me to look out of my window. There in the sky was Father Christmas on his sleigh,which was all lit up and complete with reindeer and elves ringing bells. He was waving and shouting Ho! Ho! Ho!
After he passed I tucked back into bed and fell fast asleep. As the years went by, and people explained that Father Christmas did actually exist, I was very confused as my experience had definitely not been a dream but I had seen him with my own eyes.
At about 22 and extrememly frustrated with not knowing the logic behind my experience, I ventured to ask my mom if she remembered such an event and if it had really happened.
Indeed my memory had been real, she told me. Then she explained what my childs eyes had not understood. Father Christmas, the elves and reindeer were all on top of a big truck that was driving down the street of the houses that backed onto ours! I hadnt seen the vehicle because I was so mesmorised by the sight of Father Christmas himself! True magic!
