I have had so many betta dreams
I had one where my brother bought these weird dragon/snake like fish and he puts them in my fish room and they start eating the bettas. I hit them on the heads with nets and they drop the fish and start hissing at me
So i call my mom to tell her to tell my brother to get his fish out and she says it's so great that he found a hobby.
I have a lot where I'll be doing water changes and random fish will be swimming around in the air, someone will have filled my tanks with gravel so there's only two inches of water, someone put them together, all kinds of weird stuff.
I had one where this kid (who in my dream was Juli's brother) dumped all my fish on the floor at a hotel and Julie laughs at me while I try to pick them up
Two years ago I had a betta who jumped out of his tank, but I couldn't find him, a week or so later I was in the shower and my son who was 18 months threw in this black thing, I picked it up and realized it was a dried up betta.
I still to this day have dried up bettas show up in random places in my dreams. Sometimes I'll be vaccuming up an entire floor covered with them, other times there will just be one in a cup holder in the car or something. They show up quite a bit though.
