Remember how you learned that 縛る means "to bind?" Well if you're being bound because of gold then you're tied down by money.

This word also means sleep paralysis. Just imagine if you were dreaming that your body felt like it had turned to gold and that you were tied down too.

This is a combination of the words 金 and 縛る. Both use the kun'yomi readings, but 金 becomes かな instead of かね. If you can remember that exception, this should be easy!
