Goliath, with Octopus

I'm having a scary dream last night about being thrown around and assaulted by a powerful Goliath-like figure. Then I'm watching him drag a giant octopus in a clear plastic bag around. The octopus is frozen but alive. He's going to eat it but it isn't dead. The octopus is moving, slipping out of the plastic sack.

Now I see the Goliath figure chopping up the octopus, slicing it up and each piece is still quivering. And he starts to eat a tubelike piece of it, crunching it as it fibrillates.

He turns to me and begins attacking me again. It's a scary dream because I woke up in the night and now, after sleeping again, I still remember it.
