I've had anxiety dreams, in which I discover an entire room full of herps in my home that I had somehow forgotten I had (and thus neglected), and I have to try to save them and nurse them back to health. I've also had dreams where I'm catching dozens of different species of reptiles. I've had a few where venomous snakes were brought in, in cages, and somehow got loose, and I have to try to recapture them.
The above are all recurring over the years, lol.
