to see a cow: happiness
to milk a cow: you will earn money or you will be engagement soon
to be attacked by a cow: it is a warning of some enemy whose to see a dead cow: to recover from an illness, to be free from all pains and sufferings
to see a cowshed: a hidden desire or wish
to see grazing cows: to have comfortable life
to see fat and big cow: good harvest
Good night and have dreams full of smiling cows, mooo!
