I’ve had a few weird things happen in a house I rented years ago. The owner died while building it. It had a loft with 2 bedrooms . No plumbing upstairs , just two basic bedrooms. Our bedroom was downstairs . Every single night I would hear footsteps . More so if I was home alone but I’d hear them every night unless we had a guest sleeping up there and in that case it was dead quiet. My girlfriend used to watch movies on her computer every night and she would shut the lid at bedtime which normally would shut the computer off until it was opened the next day. Out of nowhere the laptop would fire up and blare the movie she was watching right at 3am. Like full volume, laptop closed and light coming from out of the sides of the closed laptop from the screen coming on. Kind of weird but it only happened once in awhile but always at 3am. We were moving and the last weird thing to happen was I was awaken one night to the fire alarm going off in the kitchen. I jumped up and ran to open the bedroom door and the exact second I touched the door handle the alarm stopped. I went to the kitchen and it was spotless. Nothing on, no dishes out, no smoke, nothing. Looked at the stove clock and it was exactly 3am again.
