dreamt crocodile in my house

I dreamt a crocodile was in my house and was aggressive towards me. I controlled him by pushing my hand down on his snout so couldn’t open his mouth and bite me. Like a pet, I let him outside to toilet, where he caught a turtle and tried to eat it. The turtle escaped its shell and ran away. The crocodile then stood up on 2 legs and looked more human like and almost 18ft tall. He left complaining he couldn’t bite me!
