What to make of this?

First i want to say this is not MY dream. My girlfriend's sister sent me an email telling us she was coming into town to spend a weekend with us soon, and wrote that she had this dream about our daughter (her niece). She said that in her dream she was playing hide and seek with her, that she (our daughter) was hinging in dangerous places and that it was beginning to make her worry. She said our kid hid once and couldn't be found. After calling and calling out for her, she finally surfaced, crawling out from under a lawn mower - the blade area (a riding mower, maybe? idk), and that was it. The girl is really pretty, and out of the box. She's also known for usually "bringing something" with her, i.e., a new philosophy or some wild conspiracy theory to explore. She also uses a lot of symbolism in normal waking-life speech. She's supposed to be spending the weekend with us, so i just wanted to know what meaning her dream may have - or if it's just a load. Thanks in advance for any feedback!

To me it just sounds like a normal dream. I personally think you shouldn't think too much of it, but if you are worried it has a meaning, then you should just keep an eye on your daughter.
