When I entered the geological building, I felt that the light was almost poor, because there were many trees around. It's in disrepair now, so it's useless. A classmate of Grade 03 stayed there on holiday alone. As for the nameless ghost house you said, it was much ado about nothing, and I didn't see anyone take it seriously.
Therefore, superstitious things are used as a joke at most. Brother, I wish you progress in your study! If you have any questions, please contact me at qq4603 10272.
