Army Helicopters

I had this weird dream last night...

My Sister and I were driving home on 10th street, near where a church had recently burned down. Instead of the usual houses, there was a large lake on the left side of the road. Large Army Helicopters were hovering above it, lowering smaller Army Helicopters into the water. We slowed down and looked a minute or 2, decided it was suspicious and alien-related, but drove on.

Later I'm at home. My Sister didn't want to go back and look, but I did. Strangely, the only way to get back to the area was a weird interconnecting tunnel that goes from our house, through the neighbor's house and beyond...

I go through it, but I find myself in the neighbor's backyard, trying to get to the Davidson's house. On the other side of the fence is a large brown dog who wants to kill me. There is another dog as well, but he is just barking. Also, for some reason, I am shirtless.

I don't recall how I managed to get past this, but I made it back to the lake...only now it's just a large puddle in our back yard where the pool is now. It is dark, but there are a few lights trained on the puddle. Toy helicopters are hanging from something above, and several of my toys are set up to show a scene in which aliens have landed in the water, and the Army (now consisting of some transformers and my G.I. Joes) is attacking them. Some of my robot G.I. Joes now serve as Aliens.
I find myself very confused at the situation. Then I wake up.
