You all do realize that this is loosely based on medieval times. Those curtains are not light at all. They are very heavy plus you also have to add on the fact it's a blacked out curtain and the actual size of said curtain for that window.

the curtain is probably at most 10 pounds, which certainly is heavy and in a worst case scenario might cause a concussion, but she wouldn't die from it.
