This thread is giving me flashbacks from my university. I lived on campus so i got to explore at night whenever.

I don't know how to explain the feeling. I wouldn't call it peaceful. A little eerie but also kind of exciting. My campus was a bit odd. Some 'brutalist' architecture and dungeonesque parts. I miss it now.

There was a vending machine that would randomly add 10 cents to itself every couple minutes. If you waited long enough you could get something for free. Lights that would turn on by themselves. Doors that would open randomly. Might have been haunted.
