I'm curious if the tunnel is actually the body or darkness of inside the human body that our soul goes thru to get out. Also, I had been thinking heaven was a spiritual place, but it appears to me to have some physical aspects to it as well. Did you notice how your body looked? Did it look starry? When you were in the tunnel or outside of it, did you notice others, like deceased friends/relatives? What would be the most frightening thing about this whole exp.?
