I didn't see any windows either. Nothing at all. I: What did you see? E: Only the lights from I: ceiling. E: From the ceiling, yes. And sometimes the faces of the staff. I: How was it with hearing? E: Almost everything. I: How was that for you? E: Partly it was almost painful in the ears at the beginning. Especially the high-pitched sounds. When they put down tweezers or scissors or something, there was a resonance. In the head afterwards, which was not very pleasant. Also paper. When someone wrote, it rustled like that. I: Yes. E: When someone wrote something down or partly wrote on the laptop, that annoyed me. I: Yes. Did that bother you when you were sleeping or was it just annoying? E: No, it also disturbed when I was sleeping. I: Yes. Were you able to sleep well? E: No. Not at all.
