I like how you tried to figure out what the sounds possibly could be. Doing an overnight investigation at the Sallie House in Atchison, KS we heard a girl laughing and picked up someone whistling inside the house. Tried to figure out what that could have been. No little girl was out front laughing at 1:00 in the morning laughing loud enough to be heard in our location in the house, and the front porch light sensor wasn't tripped. When we recorded the whistling, we were out back on the deck taking a break and the whistling was in an upstairs bedroom...and the house was empty. Fun stuff!
Wow, being in a building with random noises definitely puts you on edge! I've been i ones where the wind slams doors on upper levels, even after figuring out the cause, it still makes you jump! Definitely looks like the first one was a hospital/nursing home at one point, decor says late 80's or early to mid 90's. I wonder if the pallets/hay were for firefighter training? Light one on fire, fill the place with smoke, and train firefighters how to search a building? Would explain all the smoke damage
