You're not too far off of my personal theory, Terry. I think that since we know so little about space-time, and also little about 4,5,6th, etc. dimensions, there could be a RATIONAL explanation, yet.
And by Rational, I mean non-super-natural.
I witnessed this shit. There's noone out there that's going to tell me it was imagined when I have 13 friends and acquaintances who have the same. However, this doesn't automatically sell me on the supernatural. It simply tells me there's more than meets the eye in the space-time we occupy.
