me and my friend went in the lecheorth tunnels that connect all the buildings [details edited per site policy]. . . in the tunnels it was around 30 degrees colder than above ground. We went with flashlights and in the tunnels the ceiling is only around 7 ft. Tall we took videos and on my friends he got this white orb surrounding my head the whole experience was creepy and I was scared the entire time. [details edited per site policy]
