Anyone else think?

I thought that too but then when I found out that the creep that was hiding within the house, I figured that he was either watching or listening to Rose's and Noah's conversation. The creep knew that Noah and Rose were becoming an item so he might have mocked Rose by saying that. I could be wrong though.

I actually thought that Noah was a ghost. It seemed odd that he wasn't acknowledged by her father once and the scene where she confronts the neighbor he had vanished moments before and then afterward he is standing in front of his van parked in front of her father's car when moments before we see her father's car and no Noah's van. But the other girl did see him. Though I thought she knew he was a ghost.
This was a bit of a weird movie.

Yeah I also thought Noah was the culprit. Another odd thing he did was when he picked Rose up in the car, he said something like he was helping his mom, then Rose told her don't you live with your father, and he was like eeehhh yeah I meant my dad but I was with my mom. It's like they wrote his character to be suspicious. But I admit the idea of him being a ghost is not bad. I don't think so, but interesting idea.
