Fish tank fish dreams

Fish dream bad dreams of needles piercing through the water penetrating their skin. No way to get out of a tank full of roomies that stink of rotten fish to the very skin. Nothing to do but ongoing laps inside a four cournered glass merky with flem. Continuous memory failure not being able to recall the previous ten minutes yet a queer feeling of dejavu lurks within. What have I been doing? Wondering wether I even existed then. The ability to question and imagine is surely a nightmare's origin to them.
