Probably the weirdest (funny) dreams I ever had were after my fish disappeared. I had a female and male beta when I was a kid. One of them jumped out of the tank and into an open drawer. I didn't find it until it was a dried up little chip (although still clearly, once a fish). After that, I had reoccurring nightmares of finding salmon under the sheets of my bed, or just finding fish in really strange locations and for some reason being HORRIFIED.
I can relate to this! I feel like fish stress dreams are a thing! I had tropical fish for a while and I would frequently have dreams where someone would go and buy a bunch of monster fish and put them in my fish tank and they'd eat my fish, or I'd have to transport them to water with only my hands, or that I'd forgotten to feed them for two years or something.. it goes on.
