A Man and a Dog

I think my house is haunted. About 7 or 6 years ago, my grandpa passed away in my house from cancer. In 2006, my dog max was hit by a car and died. Before this happened, every thing was fine. One time, I was sleeping and something tapped me so across. I woke up, looked and saw a tall man wearing jeans and a blue sweater. I blinked my eyes, I looked again and it just vanished. Another time I was outside waiting for my other dog. I was calling bailiy and there was this black dog, you could kind of make out the shape, it's hard to describe. I thought it was bailiy, she's black too, so I started to run to the dog but it vanished. I ran inside and there was bailiy. The other day, I was upstairs and watching t.v. and I felt something furry go against my leg. That's the 2nd thing happening to me when I am getting up to go to the bathroom. Another time, it was day light and again I was watching t.v. downstairs. This man walked across the window, so I ran outside to see who he was. I saw him and I yelled "hey!" but he vanished into thin air. I think it was my grandpa and my dog max's ghost.
