My workplace is meant to be haunted by the spirit of a man who died in the steel works that once existed where my office now stands. I've never seen anything, but some colleagues have.
However, My In-Law's house is definitely haunted. Its' quite an old house, & seems to be haunted by 2 children. My Sister-In-Law's bedroom & the landing are the focal point for most of the activity. I've seen the spirit of a young girl in white standing in the corner of my SIL's room. She herself has seen the girl on numerous occasions, and once the girl even flung open the bedroom door and slammed it shut. Both myself & my husband have seen shadows pass by when we were the only people in the house. My mother in Law has felt someone tap her on the shoulder when she was alone in the house, & sometimes she comes home to find all her wardrobe doors wide open when no-one has been home all day. Myself & a friend of my husband have both seen the ghost of a little boy at the bottom of the stairs too. The scariest thing that ever happened was one evening in winter when it was dark outside and the only people in the house were me and my sister in law. I heard her calling me from her bedroom so went to see what she wanted. Immediately it was like walking into a fridge and she was standing there looking terrified. when i asked what was wrong she told me to listen, and i realised then that i could hear the sound of deep breathing. we went all round the room trying to find a source of the sound, but couldn't find one, but no matter where we stood, the sound seemed to come from right behind us. Then My In-Laws came home, and my mother in law could hear it too, but as soon as my father in law came into the room it stopped. Funnily enough, my sis in law was 17 at the time, she's 24 now and as she's got older the funny goings on have all but stopped. Weird stuff seems to happen more when my nephew & neice (aged 6 & 4) are there.
