An old raintree

I dreamt of seeing a huge old raintree, suddenly, collapsing parts by parts, branch by branch, crushing a small box with four wheels. The tree broke apart slowly, intermittently, then a chrushing blow. People were around the box and started to ran away. It was quite a mess, a huge mess in fact. Within minutes, a few bigger boxes with a huge flat plate in front of it came. They cleared the mess efficiently and promptly, in a matter of minutes. It was very fast.

And i woke up.
