The weirdest thing for me was years ago, when I was a lot younger. For my 7th birthday, I got two of those helium ballons. ( I love those things, one time, they got close to the TV, and it changed the channel!)
Before I went to bed, I left them in the living room, which was of course in the front of the house. The next morning, I went into my mom bedroom, ( btw this is in the back of the house) and woke her up by holding her nose
So we watched TV. As we watched, we saw the ballons that were in the living room the night before come down the hallway. Now, if it was the wind, it would've gone right in to my room, since my room faces the hallway. But instead, the ballons stopped,
turned, lowered themselves to aviod hitting the door's archway, then, after passing that, they went up to their normal hight, right into my mother's bedroom. They then floated pass the bed and hovered in the corner of the room. True story!
