Crossing the Red Sea is the key to developing a future. In order to have a vision of the future we need to dream. If I look at another person and don't see the image of G-d writ large upon their face, I may not be in Egypt but I haven't crossed the Red Sea. If I am in Shabbos and feel irked by prohibitions, bound by rules and frustrated, I may no longer be in Egypt, but I haven't crossed the Sea. Jewish people need to dream.
Dreams are prophecies and dreamers are prophets.
He would quote the Torah from Izbicy about the Hebrew word for Bread, Lechem. The three Hebrew letters that make up the word Lechem also spell the word Lochem, which means fighting and warfare. But turn it around, and the very same three letters spell the word Cholem, Dream. So we talk of our dreams as we eat our bread. The Grace after meals we recite after eating bread is full of dreams and visions.
