We listened to the song "Made to love" by Toby Mac in my classroom. Unfortunately, we could not understand the phrase:
I know it's over 'cause my feet have hit the cold floor
Check my reflection, I ain't feelin' what I see
It's no mystery
So, we could not understand why does he talk about his feet and cold floor. We thought that it was an idiom, but we did not find something similar to it. I will be very grateful for explanation.
