I’m afraid talk_lay_awake_neutral_loop is the only talking/laying animation. You could make do with the idle_lay_exhausted_loop animation and have her talk (her lips wouldn’t move, but it’s the closest remedy). Episode doesn’t have too many laying animations to choose from.
Another thing you could do is upload a floor background and then use normal standing animations while, at the same time, making it appear as if she’s on the floor. It is a little extra, but it does help too
