The point is, I'm trying to understand the meaning of the song entitled "Just Like You" by Chromatics. And here is the except where the above-mentioned phrase is used: (the full lyrics if needed: https://genius.com/Chromatics-just-like-you-lyrics)
"He looks just like you He even says the same things He's always hanging upside down..."
So.. it doesn't seem to have a literal meaning. Maybe it means "messing around/behaving like a child", or maybe that persons sees the world differently, in their distorted way. It is probably important to know the story of the song to get its meaning, but I've failed to find any information.
I would be really grateful if you helped. Till then, thank you in advance!
