We think that Nevuah is sort of like a communication from "outer-space". This is an error. Let us examine the psukim.
הרק אך במשה דבר הלא גם בנו דבר
Did Hashem only speak IN Moshe [said Rebbetzin Miriam] He also spoke IN us.
פה אל פה אדבר בו
Mouth to mouth I will speak [said the Lord] IN him.
רוח השם דבר בי [שמואל ב כ"ג ב]
The spirit of Hashem spoke IN ME [said King David].
Prophecy comes from WITHIN not from without.
[Michtav M'eliyahu 5/ 409]
