No problem, TV!! Nottingham has been in the news this last week, hasn't it, regarding the virus? I bet, if you listened again to every radio and TV broadcast you have heard recently, stations would have been mentioned, and since it is highly likely that you have both listened to most of all of that. then your brains would have come up with something similar, particularly because of the association with Nottingham. It is coincidence of course, but always such events are interesting and remain in the memory.
As far as dreams are concerned, all my life I have had vivid, complicated dreams, casts of thousands, scenery, mainly urban or town, full of colour and action. Quite a few I can still picture in my mind, but oh dear, what a pity I have no talent for writing any of the stories and scenes they depict!!
