Yup. Broad daylight on a highway. Saw him along the side of the road, told husband to watch out for him, saw him chase after something that rolled out to the middle of the highway. Truck passed us, we passed the point where the fellow was. I looked back, nothing.
Yes. I've encountered more than one. I grew up in a huge old rambling brick Victorian house that was haunted.
Haven't actually seen a ghost but I have seen a creepy shadow leaning against the inside of my bedroom door and I guess I saw what I think they call dopplegangers of my cousin twice.
