Last night I dreamt that one of my mom's friends came over (this person was actually an entire invention of my dream) and he brought me some fish. I put them in my 10 gallon but for some reason it also had a stingray. One of the fish (it looked like a searobin but I'm not sure) started jumping up and down on the stingray then came to rest next to him. The stingray then jumped up and came down pointy end first and speared the fish. I told my mom's friend I couldn't keep the fish in there, he couldn't understand why.
