Danger Dreams

I've been having lots of dreams lately that take place on the wooden playground of my elementary/middle school.
There are always children in danger, I'm not one of them, I'm the authority.

here's one dream:

Large, metal allegator-like sculptures have been placed all around the playground. They remind me of the animal shaped fountains in the parks of my childhood; elephants shooting water out of the their trunks, hippos spitting fountains out of thier wide flat pink mouths.
But the allegators in the dream are not fountains. They are mostly just the allegator's backs and eyes, the tips of their tails, they are flat on the ground, as though the artist who made them wants to give the illusion that the rest of the allegator's body is under water.

Some of the allegators dont move, others slide back and forth, on tracks that must be under the ground. Their heads, snouts, are sharp. and the children get too close to them, as they slide back and forth too quickly.

I am sort of myself but i am also sort of a teacher. I am watching the children play on the bigger allegators and dare eachother to get too close to the sliding allegators. i have a bad feeling about it.

My friend comes to stand near me.
"theyre from that film set." she says. "the filmmaker donated them after the shoot was over. theyre for killing."
and then i remember. i saw that movie. it was a horror movie, an art film in which people are killed by allegators. the movie was low budget so the allegators were not made to look real, they looked like sculptures which make it more terrifying. they were these sculptures.

i go to the principle and try to convince him to remove the allegators but before i can explain to him why and how they are dangerous, i have to run back to rescue the children who, again are too close to the sliding sharp-snouted sculptures.
