Freud, denial and unconscious

I don't think I have any of Freud's defence mechanism, and I'm always amazed when normal people do. One of the things that blow my mind about normal human beings is denial. When I see a packing plant getting into a bad situation I'll say, "That's not going to work," and everyone will immediately think I'm being really negative. But I'm not. It would be obvious to anyone outside the situation that what they're doing isn't going to work, but people inside the bad situation can't see it because their defence mechanisms protect them from seeing it until they're ready. That's denial, and I can't understand it at all. I can't even imagine what it's like. That's because I don't have an unconscious.
