I've got a whole range of (fictional) venues that I keep visiting in dreams. The Russian city (seen from the top deck of a red London bus), the Russian train station in the middle of nowhere, the rural boarding school (that one crops up a lot), the international food market (where I never get to stop to eat)...
Oh, and I used to dream regularly of a school with a swimming pool in the basement that had a benign killer whale in it, who would give me sage and sardonic advice

.
I also have (and goodness knows why there's no escape, even in sleep) whole dreams that are just a setup for a pun. Early this morning, for example, I dreamt I was fighting (in a Jane Bondesque manner) a terrorist organisation whose aim was to stop all MTF gender transitions - they were blowing up hospitals, firebombing surgeons... the thing is, I can't tell you directly what they were called here without breaking the ToS - let's just say that in the UK there's an organisation that interferes with fox hunting who are called
The Hunt Saboteurs, and I'll leave you with the task (should you choose to accept it) of substituting a letter until... well, you'll see. Sorry.
My mind is warped, even in sleep.

That one is right up there with The Artichoke Dream, in which I and a friend were eating artichokes - my friend had never had one before, and said to me "How do you start this thing?" and I quipped "You pull the choke out..."* and she replied "That's a hearty joke..."
Sometimes I wake up shaking my head.
*Note: this may be meaningless to younglings, who have never seen a car without an automatic choke. Look it up. My age showeth.
