How is communication achieved in the dreams of deaf people and what does it show?

Language is a complex phenomenon. Probably, more complex that what you think. BTW, have you ever thought that how communication is achieved in the dreams of deaf people? Well, one might say that deaf people don't dream but they definitely do! Another might say that it is achieved through verbal languages, but that's not true. Deaf people have no understandings of verbal languages. As studies show, communication is achieved through sign languages in the dreams of deaf people. The sign languages used in their dreams is the same the sign language of their home countries. It can be American Sign Language (ASL) or any other sign languages!
As linguists believe, this shows that people are born with a blueprint for learning languages. This language can be verbal or sign language. It means that language is God gifted. To put it in more simple terms, God has given us some tools to learn languages.
Please don't hesitate to tell me what do you think of this blueprint?
