Sleep Paralysis
Temporary Paralysis
Remember how you learned that 縛る means "to bind?" Well, in Japanese being bound by gold means you're experiencing sleep paralysis, or temporary paralysis. Just imagine that you're waking from a dream where you're bound up in gold thread, and it's stopping you from moving.
かなしばり
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!
金縛りにあったことはありますか。
Have you ever had sleep paralysis before?
