Yes, excellent interpretation of the medical evidence by MOM. Gravity draws the blood down Zim’s throat if he’s on his back.
I know that sensation. I had a nosebleed so bad that the emts had to be called, and the sensation of it going down my throat was terrible. And I was standing up.
They told me to be very careful not to swallow it, as it might make me sick to my stomach. Gave me a neat nose clip, showed me exactly where to place it, and how long to keep it on.
Caused by very dry air in Minnesota winters. I keep that clip handy, just in case!
