Defend for yourself

This story has to do with me and one of my friends I will not say who this person is, but for now lets name her Anne.

Anne and I were coming home from her house after gathering some of her overnight items so she could spend the night at my house. It was a dark night, the moon full and the stars out.
As we were riding our bikes into my back yard, which is no more then an acre big. But it is surround with a big old walnut tree, a fenced in dog house, a garage, wishing well, room to drive our four wheelers, garden and room for a boat. It was loaded with places to hide.
We road our bikes right up to the big old walnut tree and no sooner then I can get off my bike I see come running out from behind the boat a figure dressed in a brown cloak with the most scariest face I have ever seen. It was hairy, wrinkly, and just not right looking. I was scared!!! Anne, who was turned away from the scary thing didn't even see it coming at first.
Everything happened so fast, that as soon as I saw this thing I was off my bike dropped everything that I had on the ground and was off running toward the back of the house screaming. By this time Emily, I mean Anne, sorry finally figured out what was going on; but I didn't not care one bit what she was doing, I was defending myself.
I reached the back door and thank goodness it was unlocked. I opened the door and literally slammed it shut on Anne. But I did not stop there I found myself running through the family room, were later I learned that is where my mom and little brother Aaron were peaking out the back window rolling with laughter from watching the whole thing go down. I made it through the kitchen, down the hall way into the the bathroom. By this time Anne was able to open the back door and make her way through the same rooms to catch up to me just in time so I can again close the bathroom door and lock it in her face.
I'm standing on the toilet while Anne is trying to open the door and bang it down. Only a few seconds pass and I finally realize I left my friend behind. I quickly unlock the door and pull her in before I shut and lock the door again.
Now, here we are two teenage girls one standing on the toilet the other standing in the bath tub both of us scared to death and tears running down our faces. We don't know what happened to this thing maybe it is trying to find us somewhere in the house or it just took off running. We were in the bathroom for maybe a minute then the banging comes, along with the laughter. "Ginger, Anne, open the door. It was only dad in his Halloween costume."
I slowly come down off the toilet, Anne makes her way out of the bathtub. I very slowly open the bathroom door to find my dad, now with his Halloween mask off still standing in his brown cloak with a red face from laughing so hard. My brother Aaron is on the floor rolling with laughter and my mom tears of laughter strolling down her face. Then there is me and Anne with white-white faces in shock.
At the time it took Anne and I a good twenty to thirty minutes to find the laughter in all of this.
Today it is now Emily and I's favorite story to tell and we tell it with laughter.
