Octopus

I dreamed that a friend and I had found a place to vacation. It had a big pond. We wuold go swimming in the pond. Occasionally there was a big fish that I wondered if it would bite, but it didn't. Then the water began to stir and get muddy. Then a tentacled arm and then more arms started coming after us, trying to pull us under. We ran to the cabin. The giant octopus could grab at us from the water, but it couldn't touch us on dry land. That's all.
