Mouth Open<br>At night time, my mouth was falling open frequently. I purchased a mouth guard in the hopes it would help. In the middle of the night, I awoke with pain in my jaw. I tried changing position several times, to no avail. I finally removed the guard and gave up.
they slept in odd positions
The text reads that they changed positions, but never mentions that their positions were anything other than ordinary. I think maybe the wording threw the system.
( z1 sleep :ARG0 ( z2 they ) :manner ( z3 position :mod ( z4 odd ) ) )
