We are actually calling it Shoddy Construction with what I know of the house:
The Previous Home owners living here before us had to get full house repairs due to a Tree falling on the house where my room is (The Picture is not my room as it was on the opposite side of the house) and the ceiling was crushed in all rooms except part of the above mentioned room. The ceiling was repaired and when we moved in, the room's ceiling was bent. After the fall of the ceiling, we saw the entire ceiling cave and saw what looks like the original ceiling.
Whoever repaired the ceiling forgot to remove the old ceiling in this room.
