I know that I can only get an impression of what they are saying in a dream. It is not an opinion.
How would it be possible to hear words? There is no sound coming through the ears!
Anyway, there is no point in arguing about it. If you THINK that you are hearing actual words, that is fine with me. I am just saying it cannot possibly happen. It is the mind that “sees” and “hears” in a dream (your eyes are definitely closed).
