Dream of

I was by the ocean with small waves, not a huge swell, and I was walking towards the water along a rocky reef. I recall I was barefoot and I happened to step on some ants and/or insects (I don't think they were crabs, they were too small), that I couldn't avoid to keep going, and they swarmed over my feet and up to my shins, but not the rest of me. They weren't biting me but that's as far as I can remember. It was a clear day.
