More on My Haunted House

Alright. I have a little interest in my ghost experiences now so I will continue with more incidences in my home.
I have a finished basement. My kids never have liked going down there. I teased them about being scared when the truth is, that there were times that I felt a little creeped out down there myself. Being one to poo poo the whole ghost thing I refused to let it get to me. I fixed it up real nice down there for the kids. They have a place of their to play video games, watch T.V. or just mess around. It's fairly nice for a basement. Carpet, drywall and a bathroom. The people that built the house supposedly lived down there while they were building the upstairs.
Things go along. The boys play down there and watch TV, etc. for a couple months with no incidences. Then one night my oldest son comes running up the stairs scared as heck. I ask him what in the world is the matter. He looks at me ready to cry and says, " Mom, I was just shutting the light off to come upstairs when I saw someones arm go around the corner of the bathroom.!" He was seriously frightened! I was like "What the heck?" We were all upstairs and my youngest son had just come up minutes earlier.
So BF and I go down to check things out and of course there is no one. BF puts it down to my son's imagination. I am not so sure. I know my son. He is level headed and not prone to an over reactive imagination.
BF absolutely did NOT believe in ghosts. But let me tell you my dear blog readers, he does now. He recently had his own personal experience with our ghost/ghosts. He doesn't tease us about our ghost experiences anymore! ( More on this later ) I still have several more incidences to tell you about before we get to my BF's big awakening..
