attacking ants

I had a dream where myself and a few others were (I guess) in a small class or something, learning from this older teacher, but we weren't in a class room we were in this nice park-like setting, out sitting on the grass. I remember us seeing huge (like the size of your hand) versions of a snail and a slug and this new creature that was like a cross between a snail & slug plus had big-ass eyeballs. ick.

Anyway I think we pissed off some ants or something, maybe we were on or near a nest, they started showing up everywhere so we moved away but no matter how far we moved they'd shortly be there.

Then I remembered running to get away, and it was like night-time, and I wasn't with anyone, and I was running through the nicely manicured grass of the park and hot little pellets of something was raining down on me. I realized the ants were attacking from under the ground, these were like malicious ants that discovered how to throw up hot little pellets of earth from beneath the surface.

I got out of the park and was in a warehouse-y area and running down the street and it was pretty dark and a car came up beside me and it was my brother and he said it wasn't safe to be alone in this area at night.
