I certainly believe in ghosts and afterlife and reincarnation. There are tons of stories and experiences out there, not to mention my own personal experiences to just blow it off as some sceptics do. The bottle looks faked in your pic lol but who knows. Lots of photos make people debate and question and argue.
Khalis i've heard steps before too in my house but that was the night after my uncles funeral when I was a teen. I could literally hear someone walking around my house, then walk into my room and walk up to my bed and just stand there. I of course had the covers over my head since I couldn;t see anyone but I could feel him, and I could hear him breathing. Freaked me out! Then I heard him walk out of my room, floors creaking and all. A minute later my mother screams because she heard the same thing. Someone walking in her room she couldn't see and breathing next to the bed. People do have their good byes to say. Why some linger I couldn't say.
Here are a couple of pics from Faux news. They did a story about a local couple who renewed their vows and had a small ceremony. In the pic they believe it is a demon who followed the man around while he was into drugs. Looks like a dog to me but the way they were standing there is no way a dog could be where it is. People have investigate the pics and the negatives and say it's authentic. You can google it to read about it but yeah it's creepy to me lol.
