I have officially given up trying to decipher what these videos mean. However, they are still just wonderful works of art. 

Although the top comment on the YouTube page says this is what it all means (thus far): 

this is the first mandragora. the one who died in 20101101. she failed to commit suicide in the bathtube, came out of the bathroom (she’s all wet and in underpants) and noticed no one is around. then she started remembering of a friend she had in the forest, the Huldra (look it up, its a nordic legend) and she imagined the Huldra being there, trying to cheer her up.

the name sever is because she was separated from her daughter, who is now the hooker in john and clump. I guess they’ll meet again.

I don’t know if this is true, but either way it’s a fantastic way to promote an artist.
