My son and I watch movies at night in the adjacent room to where my father sleeps because it is the coolest room in the house. My father refuses to turn on the air because he insists it is too expensive. The house gets over 100 degrees in the summer. So at night my son and I watch tv in the room next to his, which is my room. My son is temporarily living here because he is going thru a nasty divorce. Some nights a movie may have a sexual scene. Recently he insisted that he heard us having sex and that it was my voice he heard and it was definitely us and not the tv that he heard. He became enraged when I told him he was wrong and insisted he knew it was me. I don’t know how to handle the situation because I live in the house. I am 61 years old and can’t bear the thought of moving again. He is totally delusional, this never happened and I don’t know how to handle it. Please, are there resources to help me?
