Is it normal that after being alone i hear others thinking "he knows"
Hi, Is it normal that after being in a room with other people and talking and having conversation with them, if I leave or they leave and I am all alone, I think I hear their thoughts and briefly their voice saying "he knows". The first time it happened, I was in a dorm and I thought it was others in the dorm across the hall talking but on opening door, they said they didn't say that at all. I have tried to figure out if they are saying it or just thinking by going back or catching up with them and no one ever says they said the phrase he knows. Its weird cause its said in their voice and it feels like my thoughts. Perhaps inner voice? Psychic? Is it normal?
