The only dreams I have of my animals or similer animals are always bad. I have had a couple dreams of my first BP "Thunder". In them she is always in trouble. Either she got out or something is after her etc.. Im always trying to save her or protect her.
As for fish, my dad got me started on aquariums. I have had this dream a few times. In the dream there are huge aquariums in my garage. 2 or 3 giant display tanks. One is almost floor to rafters and cylindrical in shape. The other is long and rectangular. There is always one or two other smaller tanks sitting on a back table. All the tanks are very dirty and you can barely see into them. The filters stopped working. In the dream Im freaking out trying to get the filters working and changing the water so the fish dont die. I have no idea why they are in the garage but in the dream it seems normal for them to be there.
The only thing I can figure is that Im always so diligent with my animals. Making sure everything is right for them. I worry about them.
