Loki didn't thrash at least while trying to get out of the blankets, just trying to find an opening to extricate himself. He didn't even look scared or startled, just frowning with his eyes a dim glow of green while he picked the sheets off from around his shoulders.
"Oh. You're here," he said, seeming mildly surprised at Damian. He looked down at himself at the question, checking to make sure his limbs were in place and body intact. "No." And he was unhurt. If a human had fallen on the floor like that, they might have some bruises, but he of course didn't even have that. Loki stood up once untangled, looking around the room. "Well, this is a different setting for this... So what plot is afoot, I wonder?" Loki may as well have been musing to himself, not his usual energetic, distractive tone. He ventured toward the window, looking out to see the grounds, but those looked fairly normal, then toward Titus, who was now fairly glued by Damian's side, crouching down to look at him. "Everything seems fine..." But the tone he used seemed to hint that it meant the situation was anything but fine, he just wasn't sure how things were wrong yet.
He looked up at Damian, forearms resting on his knees easily. "Maybe you can tell me wha-"
He was cut off because Ophelia hissed again and the floor opened up underneath him. The drop was abrupt, and the floorboards closed up behind him just as quick.
Hitting the library floor wasn't gentle, but at least nothing cracked when his heavier body hit and thankfully he missed all tables and seating. He just laid there, looking annoyed up at the ceiling. "Oh, it's one of those dreams," he said to no one.
