Night time voices

I sleep with music playing, and in warmer weather, a fan on. The music provides me with something to focus on apart from the endless stream of thoughts telling me all the thing’s I’ve done wrong or things I need to do. It also provides comfort. But sometimes, even with music on, I can hear voices. Over the last few weeks, I have been hearing what sounds like men on a radio talk show, chatting about something. I can’t tell what they are saying, I don’t really care what they are discussing. I know it isn’t another radio in our house, nor is it our neighbors, as I usually start going to sleep around midnight or 1am. This doesn’t happen every night, only some nights. Last month I was sitting in the lounge room just before bed and could swear I heard our kids talking and laughing, but they were sound asleep. I know about auditory hallucinations but sometimes I worry about my mental state. And last time I went to get a new referral to a psychologist for my depression and anxiety (for which I take medication), the GP asked if I heard or saw things other people didn’t. I have been feeling quite detached a lot, and apart from everyone and everything. I don’t know what to do about it. For now, I’ll just continue to ignore it.
