Anyone experienced anything supernatural?

this all happened on the day of the total eclipse in april(?)

my boyfriend and i decided to spend the eclipse in a cemetery where his older brother is buried, so we took some snacks, crystals, incense, and water for witchy stuff. his brother was huge on Queen and David Bowie, so we played a random mix of that kinda music and laid in the grass while we watched the eclipse. when it reached totality, space oddity by bowie started playing. as we were leaving the cemetery we saw another car there with a ziggy stardust sticker on the back and thought that was interesting.

when we got back to his parent's house we found out that they had been listening to music at the same time as us, and apparently space oddity played at the exact same moment it did for us (we were both using spotify playlists, not a radio station). we sat on the floor in the living room while his family (including our dog) sat outside and talked. while he and i were talking we both felt and heard a small dog running around behind us, very very similar to how his childhood dog used to run. he'd been put down maybe a month before this. when we turned around, we realized there was nobody else in the house besides us.

we both agreed that his brother and dog had visited us and given us signs during the eclipse, which was SUPER COOL and pushed me believe in supernatural stuff even more than before lol

my great grand mother passed away a few years ago, and my mom took her sewing machine and brought it to our house so she can sew, one day she unplug it (and thats very important) because she had finished her thing, and we sat arounf the table for dinner, and while we were all eating, the sewing machine (who was at the end of the table if that makes sense) started working, all by itself, without being plugged on some electricity and the button was in "off" mode, and it happenned multiple times after, we didn't get worried, we were joking about our grandma being here to check on us etc... but now, i thin k it was really weird, it had no reason to suddenly work like that! and the thing is, it only happenned when we were ALL sat around the table, eating and everytime it was unplugged. I thought maybe the machine could have kept some electricity? but i don't think it's even possible sooo... maybe my grandma was there :)

One time I was getting ready to shower and while I was getting the bathroom set up and everything I looked up and saw what I thought was my little brother standing in the doorway to my room (My house is railroad rooms so its a straight line from the bathroom to mine).

He looked like he was caught doing something he shouldn't have and I assumed he was just touching my stuff, so I bolted to run and see what he was doing in my room. He jumped behind the wall where my bed was so he wasn't in that straight line I was running, and when I got into my room it was empty. 

I didn't know what else to do so I just walked back to the bathroom confused and saw my brother in our mom's room playing on is ipad. He just looked up at me like "Why were you running like that" and I knew that 1. There is no physical way to from my bed to my mother's without going through the doorway that I was charging at and 2. That boy had not moved anywhere from that ipad in while. 

I usually try to think of alternate explanations when spooky stuff happens to me but this really has me for a loop. I can't think of any other reason but ghosts or spirits for this one.
