I personally think that they do. There’s been far too many things that have happened to myself and my husband to declare otherwise. For example- when we first moved into our home 4 years ago, I kept thinking I was seeing someone out if the corner of my eye. I never mentioned this to my husband, until one night, I got up to use the bathroom around 2:30am, I came out of the bathroom and actually bumped into someone in my hallway. In my semi-awake state I said “oh! Excuse me.” And kept walking, then I realized what had just happened so I quickly turned around and saw no one. Now, I know I bumped into someone and I could even describe her. It was an older woman, with long gray hair to her waist, in tattered clothes. I went back to bed, thinking possibly that was some weird dream like. But, in the morning my husband said “this is going to sound silly, but do you ever see ghosts here?” I was a bit in shock that he’d mention that so I kind of shrugged it off and just said “why do you say that?” And then he went on to tell me that he keeps seeing this old woman, with long gray hair in clothes that looked quite worn. I believe we were seeing the same woman.
