The demented old man at home suddenly said that I was wearing a hat on my head. Actually, I didn't. I'm a little scared. I don't know what he saw.

I'd rather you take this as a coincidence, otherwise it's too uncomfortable. I think you might as well put on a hat and see what she says. If it is still before, it is mostly nonsense. If you still feel that you can't pass, ask for an amulet or something, or find a wise man to look at yourself and find psychological comfort. I am not afraid of anything, naturally nothing will happen, and you will be more timid and passive, hoping for peace and happiness.
