Yes, and heard. It's not quite as scary as television depicts it to be. Unless they're demonic, then it can be quite shocking. But it honestly depends on your boundaries, plus if you keep yourself open then they'll be less hesitant to show themselves.
yes ghostly experiences have been seen throughout the ages as long as humans have ever existed....mine was in Lansing Michigan, he was a helper not a harmer..he told me when my mom and her boyfriend were going to get in fights and i was not the only one who seen him...my mom did and so did her boyfriend.. her boyfriend also claimed to see the mother of the ghosts. there are 3 types,helpers, harmers,and the ones who try not to interact with people.
I haven't SEEN one, but I do have some experiences. 1. I was drawing in my room one day, and all of a sudden I smelled my gramma's perfume. I looked at my door, said "Hi Gramma" then the smell went away. 2. One day when I was getting ready for school, I heard this voice behind me when I was walking down my hallway. It said "Hello". It was a man's voice, and was sorta deep. I asked my mom if my grampa had a deep voice, and she said he did, kind of. (Both of these are true. Also, my friend used to live where I live now, and his cat died right in front of my room. I sometimes see my cat staring at that exact place when he's resting on my bed with me at night)
