Post-apocalyptic Island of Horror

Soooo...I had this dream that my bf and I inherited this mansion on a private island along with this dr with whom we were friends.  We moved in all together and started living and settling in.  There was a bridge from the island to the mainland.  Anyhoo, we were there for several days. One night, I was woken up by a noise. I looked outside and, to my horror, saw a bunch of humanoid, zombie-like creatures.

I woke up the bf and got him to look, too.  We dressed and headed to the kitchen where there was a wall of windows and looked outside as tons of the creepy critters were wandering around.  We watched as one ate a squirrel.  Our friend, the doctor (not to be confused with THE DOCTOR as in Dr. Who), was on call and had gotten called in.  He came into the kitchen to grab a bite and coffee before heading out.

"You might not want to go out there," I said.

He looked up and followed my line of vision to the windows. Needless to say, he dropped his coffee.

"Is your car in the garage?" the bf asked.

"No..." the dr. replied.

"It's weird.  They can only go as far as the drive before stopping..." I said.

"A force field of sorts, I guess," the bf said.

"I've gotta get to work," the dr. said.

We somehow managed to distract the zombie critters through the window long enough for the dr to get to his car and drive off.

Every day they disappeared completely.  No sign whatsoever on the island of anything but normal creatures. We holed up every night and made sure our cars were in the garage.

At some point, we had to hire this handyman/hunter dude and he suggested we just move as the activity got increasingly worse.

We packed at night, all night, got everything into the cars and trucks that we wanted/needed. We waited for daylight, but it never came.  Instead, a storm moved in and kept the sky dark.  The critters could apparently be out then.  We had already set explosives up in the house, so we needed to hightail it out of there.  We had no choice but to drive outta there like crazy.

We drove to the bridge, slow-moving critters chasing us all the way.  We tossed some dynamite at the bridge as we crossed and blew up the bridge just as the house blew up as well. 

And then...I woke up.  Pretty crazy.

Epic dreams, y'all!
