It's an English song that I watched in VH1 channel around 1-2 years back.
The song has a human being (I remember a mid 20-30 year old girl) in it and a mysterious creature that wanders on a mountain. It looks like a spiritual creature that's mostly transparent and walks on 2 legs.
The creature's resemblance is similar to the Pokemon Gengar but a lot bigger and with a different color(light colored).
The creature is portrayed using graphics/vfx and is definitely not portrayed by an actual person. It doesn't talk or sing during the song.
The person just follows the creature and it keeps wandering in the forest and on the mountains.
