re: What sort of "paranormal activities" have you witnessed?

I have two that stand out to me that scared me pretty good as a kid.

When I was about 10, about a week after my dad passed away, an old cordless dirt devil vacum in the laundry room turned on while we were all in the living room. This thing couldn't hold a charge and had been unplugged in a box for months. Not sure how it turned on, but it scared the living shite out of me.

About a month after that my sister (no pics) and I were at home while my mom was at the store. My parents had a jacuzzi tub so my sister was taking a bath and I was across the house in my room. I heard two loud bangs and came out of my room. My sister then came out of the bathroom yelling at me to stop being an a-hole and slamming the door. I was confused, and then scared when she pointed out that both the master bedroom and bathroom door were shut and locked (couldn't do that from the outside). No idea how that one happened either.

TL:DR - Bunch of weird shite happened after my dad passed (in the house).
