I believe there are ghosts. I don't think I've had an encounter with a ghost yet, as in seeing one. But when I was in about 7th grade me and a gf were up late. My mom usually worked afternoons and would come home. We heard the front door unlock and open then footsteps through the living room to the kitchen. My friend said whats that. I said oh its my mom. After a few mins I didnt see my mom coming in my room ( house was all 1 level and I was up past my bedtime!) I went out to check, didn't see her so I went to the door and opened it and my moms car was NOT there.
On another occasion at my old apartment there was a murder 25 years ago of a mother and son on the ground level. there was only 3 floors and we were at the top. Each section of the apartment had a door and 6 apartments spread on 3 floors. One night at about 3am we heard a very very loud knock. My husband went to the door and NOONE was there. Now also strange is I had two dogs die in that apartment. We had some horrible times and luck living there for two years. Not saying its all connected but who knows? The killer was never caught. There was also a drowning at the apartment as well as the another sucicide murder of the OWNER and his wife, but it was not at the apartment building. He was said to have been a very very evil man.
We live near a cemetry now and when my hubby watches the ghost shows hes always thinking he hears stuff or something. lol I am like " ill believe it when I see it "
