About 2:30 this morning I woke up and heard what I thought was someone outside my house yelling "BANG!" The dogs started growling and my wife twitched a little, so I quietly got up, opened the safe, got my pistol, clicked the safety off and checked on the kids, then started clearing the house. When I was sure the house was clear I made my way quietly out the back door(furthest away from the noise) and started casing the house. I didn't find anyone anywhere. Went back in the house and just as I reached my bedroom I heard it again, then again. I followed the noise to my den where my pit/lab mix was sleeping and realized the noise I heard was her sneezing. Please tell me I'm not the only one who's done this before.
