I have thought my boyfriend had said something but he hadn't but were sat next to loads of people and in other scenario loads of people were walking past us. He even did it himself this morning thinking I'd said somethin. But I woke from a dream and just milliseconds before someone was talking to me. I worry it means in hearing voices. It could've been a dream (boyfriend said this has happened to him) or someone could've walked past my room talking. Yet again another brain tumour symptom :/
