My brother, who is saved, had a strange experience. He was walking in the woods behind where he works and came to an area that looked strange to him. He said that the trees were bent in the same direction and there was a big old tree that was twisted. He thought that maybe a tornado had come through the area so he looked online to see what he could find. He read that there used to be a road that went through there that seemed to be part of a vortex. He said he got a weird feeling while he was there, but was not sure if it was just weird or evil weird. Anyone know about these vortex's?
