Can someone help me to interpret this dream I had for the first time, last night?

I was in a field of a farm, when I saw a big brown horse ( really huge) with a blanket on its back,  walking very slowly, almost in the same manner cats walk when they are hunting, slowly and with calculated movements.

In that field, there was a brown chicken, that was just there eating and scratching the soil looking for worms...

This big brown horse with a blanket on its back walked slowly to the chicken, and in an abrupt movement takes the chicken in his big mouth to kill and eat it.

When I saw this I felt surprised because I thought horses are herbivorous creatures.
The dream ended with my reaction of surprise.
