Absolutely, I believe! Anybody who lives in a 160-year-old house like I do knows that there is "something". There is just too much evidence, too much to ignore. I believe that children and animals are much more attuned to these things than the rest of us - we lose most of this sensitivity as we grow older and our lives become more sophisticated and more complicated. Those individuals who retain their strong sensitivity into adulthood are the Sylvia Brownes of this world! I know there are a lot of "wannabee's" out there, but I think she's the real thing. She's on the Montel Williams Show once a week (Wednesdays?) and I love listening to her!
I've never actually seen anything in my little house ... but my dogs have. This house was built in the late 1840's and was occupied continually from 1850 until about five years ago by members of the same family! I moved in 4-1/2 years ago. I'm the first one to ever live in this house that wasn't a member of that family! My dogs were always watching things that I couldn't see! My older Boston, Rudy, flat out refused to even enter the big old-fashioned back bedroom. If I was working back there, she and Ragan, my younger Boston, would sit nervously in the doorway, both of them watching something move around the edges of the room! Both of their little heads would move in perfect unison, both sets of eyes following exactly the same thing - and I saw nothing! They did the same thing in the living room several times, sitting on the sofa watching something go diagonally across the ceiling. Sometimes I got the impression they did it on purpose, just to creep me out! After a few months, they stopped doing that and never did it again. I always thought it maybe was a "family member" who just wanted to make sure I was taking good care of the house. There have been a few other unexplainable dog-related incidents, one just a few months ago, but they're more mischievious, teasing kind of things.
I don't believe any of it can hurt you, but I've known too many people who have had things happen not to believe. My former boss, who lived in a house about the same age as mine, had all kinds of weird thing happen. Every morning about the same time he'd see, out of the corner of his eye, a tall elderly man in an old fashioned business suit walking down the central hallway towards the front door! If he purposely sat and watched for it, he'd never see it. He finally got so used to it, he'd just say, "Good morning" to him and go on about his business! And years ago my brother and sister in law lived in an upstairs garage apartment a block from the beach in New Smyrna Beach, FL where they were constantly having weird things going on - footsteps coming up the wooden outside stairs, stopping outside the door ... nobody there. Or they'd hear footsteps going down the hallway at night and then my nephew (6 months old at the time) would wake up and start crying! One BIG reason they moved!
Yep, I am definitely a believer!
