Not my experience exactly, but my mother grew up in this huge multi-family house that had been converted into a bunch of apartments in Brooklyn. She and her brother and my grandparents lived upstairs, and all my grandma's siblings and their kids lived in the downstairs apartments. She SWEARS upon everything holy that this happened, as does her brother and all of the cousins.
She said she used to hear this quiet music sometimes, and when she tried to go downstairs to see where it was coming from, she would "float" down, as if someone picked her up and was carrying her. She thought it was just her for awhile until she told one of the cousins about it, and the same thing had happened to her. Turns out it happened to all of the kids a few times. Once it happened while five of them were together, and they spent a whole afternoon just playing... running up the stairs and being "floated" down.
I teased her a couple times and asked if they didn't all have a little *puff puff* of anything before soaring down stairwells, but she's very serious about it -- they all are. If it didn't happen, they certainly believe it did.
Maybe they all just had wild imaginations... I dunno.
I'm a skeptic until I see/experience something for myself, but I must admit I have this fascination with the idea of going all around Europe for like a month, touring supposedly haunted historical sites.
