Thanks Thais!
Then nesyta, there were some mistakes I edited, like the imperative form of the verb "rêver", and the futur tense which I edited with present tense for the verb "neiger", because in French a proposition with "si" is NEVER followed by the future tense, it can be followed only with imperfect tense, or present tense.("s'il neigeait", or s'il neige"
