They take the lyrics literally and hilarity ensues. They even made their hair and makeup people headbang! 😉😉

You got Jiu right! Yea the self-made MVs were done because they were bored waiting to film on music shows and decided to do something fun. There's a few of them, where they act out the lyrics. The three main ones are Sahara, Break the Wall, and Poison Love. If you want to do Break the Wall, then you should also do the Live Showcase version first. It's a really powerful performance and the Break the Wall self MV is, as you said, so unserious, lol. Just search for "[ENG LYRICS] Dreamcatcher (드림캐쳐) - Break The Wall Live Showcase (1080P)" and it will be on Andrew Lee's channel. It has English subs as well. Poison Love is a bit different as it tells a story in the Sub-Titles. It's the first album where Handong is back from China so the Self-Made MV is all of them falling for Handong, including Handong herself. It's really funny.

They've done a lot of self-made music video but my favorite one is 'The curse of spider'! Unfortunately it's not uploaded on their youtube channel since it was shown in their fanmeeting, but there are fancams of it! And it's even more funnier with the sounds of other Somnias reacting to it together lol! If you like these kind of mvs I recommend you to watch it also!
