Mischievious Spirit Is Happy Steele is Back Home

We believe that we have a spirit that lives in our home.  He's been there since we bought the house in 2006 and we call him "Suma."  He's never done anything destructive, but we've seen doors open, heard dog toys squeak in the middle of the night, had items move around the house, and a few other unexplained things that we chalk up to "Suma."

While we were gone over the weekend, "Suma" seems to have been up to his old tricks.  When we came into the house yesterday afternoon, the surround sound system was on and up and full blast on "AM Radio" - so it was nothing but static.  Then, last night, as I slept, my fully charged phone placed on the nightstand next to me was completely dead by 2:30am.  Ahh "Suma"....up to his old tricks.  Maybe he's just glad we're back home.

Have YOU had any run-ins with spirits/ghosts in your home?
