I find that all of my dreams have some sort of meaning to them. I also have noticed that it's T's who tend to mostly characterize dreams as absolute meaningless nonsense.
You can argue that because I lead with Ne that I can find patterns in anything, meaningless or not. But there is much more to it than that. I am very in tune with my internal map of symbols, and intuiting meaning from my dreams seems nearly as direct as listening to myself think. They help me solve problems and get the lowdown on what's going on in my depths.
When I have dreams in an odd mental state, like when fevered, my dreams lack that versimilitude that normal dreaming has. It's not that the imagery is too bizarre to relate to, it just doesn't ring as connected to anything. And when I have imagery appear to me in a hypnagogic state, that reads to me as utter nonsense, with very little meaningful connection to my subconscious at all. Occasionally I have dreams that seems to invade my consciousness from an external source.
What kind of relationships do you NFs have with your dreams?
