I absolutely believe in ghosts! In fact, its so weird you asked this because I had an experience last night I was going to write about today.
Last night while sitting on my couch, reading on my e-reader I heard a girl yawning. The house was dead quiet except for the clock on the wall ticking away, when heard a faint yawning sound and shuffling of feet. I ignored it at first, thinking it was my 3 yr old daughter who snuck downstairs. She was yawning so I hoped she would just go back upstairs on her own. After a few minutes of dead silence again, I heard another yawn. It sounded different from the first, but definately a yawn. So I started calling her, "Bella, go back to bed". I heard nothing, which I usually hear her moving around, trying to run back upstairs before being caught, but I heard silence. So, I put my e-reader down and walked through the house to find nothing, upon checking upstairs my daughter was fast asleep in her bed. I thought I was losing my mind, but I know what I heard. After returning back down stairs to finish my book, I found a droplet of water, that looked like a tear, on my e-reader. I stared at it, baffled. Thats when I knew, I had some sort of experience of the paranormal nature.
Its not the freakiest thing thats every happened to me, and it may not sound like much, but it defintly spooked me!
