Dream of child, children

I got into my 20 year old jeep to discover it was parked at the top of a very steep hill facing down. I thought it was going to tumble over and tried to ask a man passing to help but he walked on. I instinctively and slowly released the handbrake and it began to roll - it was ok. I got out at the bottom of the hill where there was a garage? Then I noticed the tyres were almost completely gone - they were done to the metal like they'd been attacked with acid or ripped away. I wondered who would do that to my car, but left it there and went on into a large room where people were. Some of them I knew from voluntary work I do. There were lots of children playing on an escalator/slide - I told them to take their shoes off, which they did but left them on the escalator where they slid everywhere. I walked over to another moving floor where other were playing - It developed pleats/ waves and swallowed up one of them. The child seemed to be all right though as if she didn't panic. I kept thinking I should be doing more but wasn't sure what or how to manage it all.
