It Was a Dark and Freaky Night...and yes, I did it to myself

I've been staying with a great-aunt who needs constant compaionship because senility has set its hooks, forcing twenty-four/seven supervision and the purchase of enormous clock faces.
That is another story.
My tale involves ghosts and the home's central heating system.
This house is haunted.
No one believes me, I know that, but still, it's true. I don't sleep well in her home because of the random noises that attack my central nervous system and make me as uneasy as if I were schizophrenic.
I've heard doors shutting mysteriously at three in the morning, and upon stealthy inspection of the living room, of course I was armed with a bottle of Keri lotion (thought patterns are illogical when ghost hunting), I found no warm bodies straying into the kitchen for midnight treats.
I feel like I am being watched when I am lying in bed facing the window, so I have begun sleeping facing the door.
More recently the noises were so freaky that I've started leaving the television on all night, muted, but the thing is so old it has an ominous hum all its own. But it also has no remote -- it's a push button television, imagine that! -- so I put up with the hum.
I've heard that when ghosts are present the air turns cooler in that area. Imagine when I woke the other morning and saw my breath! I was terrified to open my eyes as I was sure I would be ringed in ghosts like the poor dentist in "Ghost Town" (cute movie, by the way, shameless plug) and it turned out the the aunt had stumbled into the hallway and after having a normal routine of keeping her home at a balmy 82, I kid you not, she decided to turn off the heater on this particuls night in order to save a few pennies. It was twenty-eight degrees outside and the thermostat read 65 when I finally sprinted to the controls to dispel my ghosts.
BUT! And here's the crux of my tale...the other night I heard a BELL! A RINGING bell! Like a CHIMING, RINGING bell! Three tones in a row! At six a.m. Thus I was UP and AWAKE at six a.m! Not even the octogenarian aunt was awake.
Plus! Plus! I've started watching an A&E show called "Paranormal State." So now I sleep after the scary show, with the television humming, extra blankets stuffed at the foot of the bed should the old lady get stingy again, and a night light. And I'm not even ashamed of it!
Sad.
