Scott M,
When I was in my younger years, I lived in a 500 year old building in Old San Juan, Puerto Rico. I remember one evening, just after dinner, seeing a spanish soldier in a hallway of our house. Now, I know that Spain has a military... but since when have they had forces wearing 500 year old attire on US soil that disappear when you take a second glance at them?
Also, in 1998, shortly after my mother passed away, I was sleeping one night. It was a restless night. I could not sleep to save my life. Finally, I just said "to hell with it" closed my eyes and tried once more. I started to hear screams and someone was choking me. When I opened my eyes immediately, the screams stopped, but someone was still choking me. There was no one there. Finally, I punched at the air, and it stopped.
