What do you think is the meaning of my dream?

A dream expresses what your brain knows about itself and what is inside it, not about other people. The implicaions of this dream are clear. You mention "relationship" in essence three times in this question. Obviously that is what is on your waking mind and your subconcious mind. Your waking mind is telling yu you are not looking to be in a relationship for 5 years. Your subconcious is telling you that even though the thought of having a relationship is getting a chilly reception, its ppossible that flowers will bloom in the winter of your resistance. The foreign language youa re leaning is the language of love. The beautiful blonde means that you know that you are attractive to others and this is going to be your undoing. This wilderness you are entering is a little wild and not under your control. So even though you think you have a 5 year plan in full force and effect your subconcious is warning you that the heart wants what the heart wants.
