I don't think I have ever had the loo dream or teeth falling out dream or exam dream (but I quite enjoy a good exam, so they're mostly not associated with anxiety for me.)
I used to have running away dreams a lot. As a child, I had a lot of nightmares about being chased by wolves, but when I was about 7 or so, I learnt to lucid dream (not that I had any idea it had such a term,) and could rewind the dream a bit until I could climb a massive wall across the path and make friends with the wolves. Though in real life, even as an adult, I'm not a fan of wolves.
As an adult, I had many running away dreams where I was running away from various people. Never sure why or who. The terrain varies - sometimes grassy green countryside, other times more sandy, rocky, rough ground. Haven't had one of those for ages, though.
I used to dream about my father dieing. Haven't had one of those since he actually died, though.
I've also had many dreams about extra rooms. Never the same house, as far as I'm aware.
Water also features a lot in my dreams, but as it also features a lot in my life (I swim a lot,) this has never seemed remarkable. The nature if the water can vary a lot - swimming in cold seas near cliffs, paddling about in clear chalk stream with it sparkling in the sun, driving down a steep road to the sea, floating along a river - all sorts.
I'm quite often naked in dreams, too, but it's not usually in an embarrassing way, just that I don't have clothes on and it's absolutely fine (and I tend to be slimmer with clear skin and fantastically conditioned hair in my dreams, not quite like real life!)
My dreams can be very active with a cast of thousands, and I can wake up feeling exhausted. And always in colour.
I quite often dream about work colleagues. A few nights ago, I dreamt about our lovely Dutch director coming into the office when I was the only one left working - he had a red shirt on, but when he got closer and sat next to me, I realised he was wearing a red dress, and it wasn't a good fit, so was pulling all out of shape. I woke up quite upset because he normally dresses well, so I was annoyed that he wasn't putting the same care into wearing a dress. I am also not sure why I was dreaming about him wearing a dress at all, or what my subconscious is trying to tell me about what I currently think about him. Nice shade of red, though.
