I have been with a number of people when they died. More than once, they have spoken of things they were seeing which sounded "heavenly" (i.e. beings in the room no one else could see or "visions" of what was beyond). Many times, at the moment of death, I have seen individuals sit up on their death bed and reach up, as though someone was reaching down to them.
I have also personally seen paranormal activity. For about six months, we lived in a "haunted" house - of course we didn't know it was "haunted" till after we moved in. Things happened in that house that could not be explained, (and I honestly tried to find an explanation). Things moved around and stacked up in the middle of rooms. One day I walked into the kitchen and all our steak knives where jammed into the door frame around our pantry. Objects flew across the room and crashed into the wall. Clothing in the laundry basket would be ripped to shreds, (not all the clothes - it would be one shirt ripped to shreds in a basket full of clothes). I saw all these things and many others with my own eyes.
All of these things and events convinces me there is an unseen spiritual world all around us. I am a Christian, but even if I was an atheist, I would be hard pressed in the light of these happenings to deny the spiritual aspect of the world we live in.
