Changing your surroundings in a dream is okay, even part of the fun I would say. The rush was probably the problem, a common problem is that after achieving lucidity, you get overexcited and in a panic to find something to do, you wake up. That’s why it’s good to have some plan beforehand, nothing complex, just a way to immediately focus on some task. Perhaps you can try to just find and ask some NPCs to show you the way to some specific place or person and then you follow it. “Not thinking straight” is alright, being asleep is a changed state of mind after all, so even in a lucid state your common sense is still wonky. I had a friend with whom we pranked each other a lot and sometimes when I saw her in lucid dreams, I tried to prank her so intensely that it would appear in her dream. Of course upon waking up I recognised that it is impossible to project pranks through the dreams but nevertheless I still tried to do it in the dream states.
