A folk music video someone posted on Twitter many years ago, when the service was young.
It shows a young lady walking with an animated baloon across black and white streets. She turns the scenario colorful as she walks, makes sad people smile, everything is very dreamlike. The video mixes real footage and cartoon animation.
She's actually dreaming. At the end of the video she wakes up tied to a bed with a guy by her side injecting into her blood some drug which makes her dizzy. She falls into sleep again as the guy slips is hand under her skirt.
I suspect the music video may be actually a graduation project with some third-party folk song. I'm trying to identify the video. The song may have been from Mallu Magalhães or a parody made at the time, but this is not one of her videos.
