I've had these in the past. The first time I had them it Dancing With The Moonlit Knight by Genesis, I was just convinced someone was playing it very loudly.
Then it turned into Dire Straits - Money for Nothing.
The most recent time, and hopefully the very last, about a year ago it was Game Show themes.
I've had visual hallucinations as well. I was spending my days lying in bed feeling ill and I was convinced someone was writing on my bedroom ceiling from outside, using some sort of laser pointer.
I looked out of the window and even saw someone doing it.
I ended up in hospital that day and I was convinced the nurses were insulting me. I even tried to make a dash for it to go to the police, got stopped by security.
