[_paralyzed_]

I think you found remnants of somebodies model train display. You see, as the train came round the bend and out of the tunnel it would cross through the field and lights would come on. Then the train would stop and let the passengers out onto a motorized pad. The pad would move the people into the steam room at which time the disco ball was activated, entrancing the passengers so they wouldn't realize the sauna was just to "soften them up" before being strapped to the motorized table in the torture chamber. Man, you've really got to look out for model train enthusiasts these days.
