Language – foreign or strange
One function of dreams is to bring aspects of our thinking and feeling which may be ill defined, toward clarification. Foreign or strange language may therefore illustrate something which is being communicated to us from within, but is still not clear. The unconscious, as in speaking in tongues – glossolalia – and of course in dreams, frequently moves toward clear awareness in stages. The strange language is a halfway house toward focused critical awareness, as is a dream. If we bring focused attention to these, as explained in processing dreams, the next step, clear verbal expression, can be reached.

Speaking in language we are learning: The language is becoming habitual, making it possible to think in it. See: speaking and using the voice.
