Haunted House

I came home Halloween night to a dark, empty house, I unlocked the door, stepped into the mudroom, felt around for the light switch, and heard the water pump running. It continued to run as I hung up my keys, and then I noticed that it sounded funny, like it was sucking air, not water. I have no idea how it works, I couldn't find any on/off buttons, so I unplugged it and plugged it back in, hoping that it would reset itself, it didn't work, so I unplugged it and made my way upstairs. I turned the front light on outside so trick or treaters would know I was home. I noticed that the stove light was flashing, the power must have gone out...again. Then I heard voices, Hurray the first trick or treaters were here! But no one came up the steps, and there was no car in the driveway and I could see no one outside. So I listened closer, it was coming from the bedroom, for a moment my heart skipped a beat, but I quickly realized when the music started that it was just Andrews clock radio. "It must have turned on in the power surge, I've never noticed it do that before". I made my way to the bedroom, thinking, "this is what happens in horror movies, people come home to dark houses, there's a clue (running pump), then they get lured somewhere, and their logic shuts off, and as they reach for the clock radio someone reaches from under the bed, and slits their Achilles tendon so they can't run away". I hit the off button with one hand, clutching my cell phone in the other.
