The Lights Festival?

So heres my thoughts. I’ve never been. It looks like so much fun. It reminds me of Tangled. It’s literally like a dream come true!! A fantastic moment/memory that MUST be lived!! Although, I did notice that people can even personalize their own lanterns! But my question is, is this just because? For whatever reason that may set your heart on fire? Or is there a sole purpose for this festival? If or if not, it is a remarkable memory that I feel would be the highlight of my life. If anyone has ever gone to this festival or anymore festivals that my poor unfortunate soul has not heard of, please leave me some feedback. I want to know about  the experience from others.
