Why is it difficult to sleep at night when staying alone in a hotel? Feeling insecure, always unable to sleep?

Why do you stay in the hotel alone? At night. Sleep difficulties. I can't sleep without security. I think this is a normal person's reaction. Ordinary people will feel this way even if they change to a strange place, especially when staying in a hotel. As I said now, some people will have some voyeurism and voyeurism, so it is normal to sleep restlessly. I feel this way when I sleep in a hotel, and I feel particularly insecure.
