I have just one quick story to share, in reference to your so-called "Shadow People". I just wanted to tell you that I have seen these things as well throughout my life, so I do not think that any of what you've had to say is anything of which is "too make-believe", or at least too out there, at least for the likes of me, as I have had my own experiences with seeing them throughout my life.
It all started when I was 18 living in Lincoln, Nebraska. I was injured in a near fatal car accident, resulting in a coma for 3 months straight. I had gotten some time away from college and wanted to get together with a few of my friends, as we were planning a little get-together, going to this little outdoor event, of which had had a lot of our favorite bands which were going to play together. I had gotten some Heineken and had been having a grand old time, thinking about all the fun that we were going to have, when someone decided to run a red light just as I was looking down, and smashed right into the front of me.
While in a coma, (I will have you know, I discovered that there is a world outside of the one in which we are presently living) many times I can remember leaving my body and walking around the hospital and seeing these shadows, in a way they are a bit hard to describe, but I would watch them as they would wait around for someone to flat line, and then grab them as they left their bodies and take them away. So are they Ghosts? Are they this, that, and the other thing? I would have to say no. And the people of whom had left their bodies; I might add they did not seem at all very pleased to be greeted by, taken away by these things ? I believe they are in no way anything good!
I do not know why I seen these things, though I do remember them very well. And I have seen them ever since, as well as what seems to be "ghosts". Now the only question that I have is "Has anyone else ever experienced anything at all similar to this?" Could it have somehow been related to my injury, or what might have caused these things? As I have said, I can now see people from time to time, who seem to be aware that I am able to see them, and they are very transparent - They just kind of wander about.
